In above related commit, uBO was modified to cache the URL of the
last clicked link, and to use this cached URL to test for the
legitimacy of the newly opened tab.
The current commit add back a test against the URL of the last
clicked link to avoid false positives when navigating from within
the newly opened tab.

Sometimes a tab event may fire for a tab which is not
yet known to uBO. In such case, bind the tab internally
so that it can be processed properly in the future.
In the static network filtering engine (snfe), the
compiling-related code was spread across two classes.
This commit makes it so that all the compiling-related
code is in FilterCompiler class, which clear purpose is
to compile raw filters into a form which can be persisted
and later fed to the snfe with no parsing overhead.
To compile raw static network filter, the new approach is:
snfe.createCompiler(parser);
Then for each single raw filter to compile:
compiler.compile(parser, writer);
The caller is responsible to keep a reference to the
compiler instance for as long as it is needed. This removes
the need for the clunky code used to keep an instance of
compiler alive in the snfe.
Additionally, snfe.tokenHistograms() has been moved to
benchmarks.js, as it has no dependency on the snfe, it's
just a utility function.
The code exported to nodejs package was revised to use modern
JavaScript syntax. A few issues were fixed at the same time.
The exported classes are:
- DynamicHostRuleFiltering
- DynamicURLRuleFiltering
- DynamicSwitchRuleFiltering
These related to the content the of "My rules" pane in the
uBlock Origin extension.

The changes are enough to fulfill the related issue.
A new platform has been added in order to allow for building
a NodeJS package. From the root of the project:
./tools/make-nodejs
This will create new uBlock0.nodejs directory in the
./dist/build directory, which is a valid NodeJS package.
From the root of the package, you can try:
node test
This will instantiate a static network filtering engine,
populated by easylist and easyprivacy, which can be used
to match network requests by filling the appropriate
filtering context object.
The test.js file contains code which is typical example
of usage of the package.
Limitations: the NodeJS package can't execute the WASM
versions of the code since the WASM module requires the
use of fetch(), which is not available in NodeJS.
This is a first pass at modularizing the codebase, and
while at it a number of opportunistic small rewrites
have also been made.
This commit requires the minimum supported version for
Chromium and Firefox be raised to 61 and 60 respectively.
The title of tabs in uBO is solely to have a better
presentation in the logger -- no other purpose.
This commit simplify keeping track of the titles, from
an active approach by directly querying it from tabs
whenever a change occurs, to a passive approach by
storing it when the title string become available in
some tab event handlers.

Additionally, a small (experimental) widget has been added
to emphasize/de-emphasize rows which have 3rd-party
scripts/frames, so as to more easily identify which rows
are "affected" by 3rd-party scripts and/or frames.
Tooltip localization for the new widget is not available
yet as I want wait for the feature to be fully settled.
Content scripts can't properly look up effective context
for sandboxed frames. This commit add ability to extract
effective context from already existing store of frames
used for each tab.

Not much can be done beside reporting to tabless network
requests to all tabs for which the context is a match.
A short term local cache is used to avoid having to iterate
through all existing tabs for each tabless network request
just to find and report to the matching ones -- users
reporting having a lot of opened tabs at once is not so
uncommon.

For static filter `popup` filter purpose, the URL of the
embedded frame from which the popup was launched will
be used in the matching algorithm.
While testing for the new `elemhide` option using ABP's
test page[1], I found out that the placeholder of the
blocked image on that page was not properly collapsed
by uBO.
The reason was because the page is very simple and
flushing the blocked-elements cache at
webNavigation.onCommitted time was causing the loss
of information collected between
webRequest.onBeforeRequest and
webNavigation.onCommitted, preventing uBO from
properly collapsing the placeholders.
The blocked-elements cache is now flushed
ONLY at webRequest.onBeforeRequest time.

No need to store mouse coordinates in background
page, thus no need to post mouse coordinates
information for every click.
Rename/group element picker arguments and popup
arguments separately.

The color value for the icon badge is now
"attached" to the blocking profile value.
Additionally, as per feedback, `3p` rules
will be relaxing before master JavaScript
switch rules.

Additionally, the `3p` rule has been made distinct from
`3p-script`/`3p-frame` for the purpose of
"Relax blocking mode" command.
The badge color will hint at the current blocking mode.
There are four colors for the four following blocking
modes:
- JavaScript wholly disabled
- All 3rd parties blocked
- 3rd-party scripts and frames blocked
- None of the above
The default badge color will be used when JavaScript is not
wholly disabled and when there are no rules for `3p`,
`3p-script` or `3p-frame`.
A new advanced setting has been added to let the user choose
the badge colors for the various blocking modes,
`blockingProfileColors`. The value *must* be a sequence of
4 valid CSS color values that match 6 hexadecimal digits
prefixed with`#` -- anything else will be ignored.

The `behnind-the-scene` context was wrongly used to
evaluate the whitelist status of the context of tabless
network requests. The document origin must be used
instead when it's available.
Additionally, much code has been revisited for better
ES6 syntax compliance.
The motivations for the re-arrangement:
- Reducing the number of entry points:
matchStringExactString() has been removed and
matchString() is simply reused with a modifier parameter
to enable matching variants.
- Presumption that most matches, if any, occur early with
the left-most tokens in a URL. This gives a very small
marginal performance gain as per built-in benchmark.
Performance-related work: the logger data has been decoupled
from the DOM -- inspired from CodeMirror's way of efficiently
handling large amout of text data.
This decoupling now makes the logger highly efficient CPU- and
memory-wise, and open the way to more possibilities.
Ability to configure some aspect of the logger behavior and
visuals:
- The hard-coded limit of 5000 entries has been
removed and is now replaced with a variety of
user-configurable settings to enforce the discarding of
logger entries.
- Some columns in the logger output can now be hidden.
The filter list look-up feature has been merged into the
existing overlay dialog used to create URL rules or static
filters, as an entry in a new "Details" pane.

The minimum version supported on Firefox has been bumped
up to 55.0.
- Default to being detached
- Default to "Current tab"
- Append current tab title to "Current tab" entry
- Avoid iterating through all tabs when no change
