Further modularize uBO's codebase
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/1664

Modularization is a necessary step toward possibly publishing
a more complete nodejs package to allow using uBO's filtering
capabilities outside of the uBO extension.

Additionally, as per feedback, remove undue usage of console
output as per feedback:

Modularize codebase with export/import
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/1664

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.

Add new filter option queryprune=
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/760

The purpose of this new network filter option is to remove
query parameters form the URL of network requests.

The name `queryprune` has been picked over `querystrip`
since the purpose of the option is to remove some
parameters from the URL rather than all parameters.

`queryprune` is a modifier option (like `csp`) in that it
does not cause a network request to be blocked but rather
modified before being emitted.

`queryprune` must be assigned a value, which value will
determine which parameters from a query string will be
removed. The syntax for the value is that of regular
expression *except* for the following rules:

- do not wrap the regex directive between `/`
- do not use regex special values `^` and `$`
- do not use literal comma character in the value,
  though you can use hex-encoded version, `\x2c`
- to match the start of a query parameter, prepend `|`
- to match the end of a query parameter, append `|`

`queryprune` regex-like values will be tested against each
key-value parameter pair as `[key]=[value]` string. This
way you can prune according to either the key, the value,
or both.

This commit introduces the concept of modifier filter
options, which as of now are:

- `csp=`
- `queryprune=`

They both work in similar way when used with `important`
option or when used in exception filters. Modifier
options can apply to any network requests, hence the
logger reports the type of the network requests, and no
longer use the modifier as the type, i.e. `csp` filters
are no longer reported as requests of type `csp`.

Though modifier options can apply to any network requests,
for the time being the `csp=` modifier option still apply
only to top or embedded (frame) documents, just as before.
In some future we may want to apply `csp=` directives to
network requests of type script, to control the behavior
of service workers for example.

A new built-in filter expression has been added to the
logger: "modified", which allow to see all the network
requests which were modified before being emitted. The
translation work for this new option will be available
in a future commit.

Grand refactoring of the logger
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.

Other issues addressed during refactoring:
- https://github.com/uBlockOrigin/uBlock-issues/issues/280
- https://github.com/gorhill/uBlock/issues/1999

The minimum version supported on Firefox has been bumped
up to 55.0.
