The Promise chain was not properly designed for WASM module
loading. This became apparent when removing WASM modules
from Opera build[1].
The problem was that errors thrown by fetch() -- used to
load WASM modules -- were not properly handled.
[1] Opera refuses updating uBO if there are unrecognized file
types in the package, and `.wasm`/`.wat` files are not
recognized by Opera uploader.

The erroneous behavior was to compute the URL of a sublist as
relative to the URL of the root list, which may differ from the
URL of a parent list.
Those spurious disconnections have been observed to occur at
uBO's launch time.

I have observed that this fixes an issue observed on Firefox 64
(current stable).
The reported Waterfox issue *may* be fixed as a result. If not,
the issue he still considered fixed as Waterfox is not
officially supported.

The advanced setting `cacheStorageAPI` has been added to allow
a user to force the use of IndexedDB as cache storage. Set to
`IndexedDB` to force use of IndexedDB. Default to `unset`.
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.

A new advanced settings has been added: `autoCommentFilterTemplate`.
Default value is `{{date}} {{origin}}`.
Placeholders are identified by `{{...}}`. There are currently
only three placeholders supported:
- `{{date}}`: will be replaced with current date
- `{{time}}`: will be replaced with current time
- `{{origin}}`: will be replaced with site information on which
the filter(s) was created
If no placeholder is found in `autoCommentFilterTemplate`, this
will disable auto-commenting. So one can use `-` to disable
auto-commenting.
Additionally, if auto-commenting is enabled, uBO will not emit a
comment if an emitted comment would be a duplicate of the last
one found in the user filter list.
The DOM surveyor will now use time-based logic to spread its work
over time. This allows the surveying to better scale down on
slower devices.
Additionally, the DOM surveyor code has been reworked to lower as
much as possible memory churning when collating nodes to survey.
This rework has been motivated after profiling the "monstrous DOM"
seen in the following page:
<https://doc.rust-lang.org/std/iter/trait.Iterator.html>
The idea is that making the DOM surveyor efficient on such
"monstrous DOM" case should make it efficient everywhere in
practice.
- Avoid concatenating with empty array: though the concatenated
array is empty, this still forces the creation of a whole new
array as per semantic of Array.prototype.concat().
<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/concat>
- Do not convert arrays to strings when sending data to
main process in surveyPhase1(): I no longer see any benefit
doing so in profiling data (if I recall properly this was
benefiting Firefox, but I can't remember for sure anymore why
I chose to do so back then).

This commit further increases uBO's procedural cosmetic filters
Adguard's cosmetic filter syntax -- specifically those procedural
cosmetic filters where plain CSS selectors appeared following
a procedural oeprator (this was rejected as invalid by uBO).
Also, experimental support for `:watch-attrs` procedural
operator, as discussed in <https://github.com/uBlockOrigin/uBlock-issues/issues/341#issuecomment-449765525>.
Support may be dropped before next release depending on whether
a better solution is suggested.
Additionally, the usual opportunistic refactoring toward ES6
syntax.

This was brought into the issue above but I ended up forgotting
about it after I focused mostly on the second issue brought up
in there.

back up draft work toward experimenting with wasm hntries
<https://github.com/gorhill/uBlock/issues/3436>: a new per-site switch
has been added, no-scripting, which purpose is to wholly disable/enable
javascript for a given site. This new switch has precedence over all
other ways javascript can be disabled, including precedence over dynamic
filtering rules.
The popup panel will report the number of script resources which have
been seen by uBO for the current page. There is a minor inaccuracy to
be fixed regarding the count, and which fix requires to extend request
journaling.
<https://github.com/gorhill/uBlock/issues/308>: the `noscript` tags will
now be respected when the new no-scripting switch is in effect on a given
site.
A default setting has been added to the _Settings_ pane to
disable/enable globally the new no-script switch, such that one can
work in default-deny mode regarding javascript execution.
<https://github.com/uBlockOrigin/uBlock-issues/issues/155>: a new
hidden setting, `requestJournalProcessPeriod`, has been added to
allow controlling the delay before uBO internally process it's
network request journal queue. Default to 1000 (milliseconds).
