Until uBO's filtering engines are properly initialized, there will
be a distinct toolbar icon to help users understand that uBO may
not be fully initialized when a webpage is loaded -- often the
cause of improper filtering of trackers/ads at browser launch.
DNR API does not support block-then-redirect concept, hence no
point in generating a DNR block rule for `redirect=` filters.
Additionally, better handle orphaned filter anchors (`||`, `|`).
This commits add the ability to open html/css/script
resources from the logger, as a formatted and syntax-
highligthed document.
The goal is to make it easier for filter list authors to
investigate filter-related issues.

Example of usage:
/img[a-z]{3,5}\.buzz/##+js(nowoif)
Use sparingly, when no other solution is practical from a maintenance point
of view -- keeping in mind that uBO has to iterate through all the regex-based
values, unlike plain hosyname or entity-based values which are mere lookups.

Example of usage:
@@*$ghide,domain=/img[a-z]{3,5}\.buzz/
Regex-based domain values can be negated just like plain or
entity-based values:
*$domain=~/regex.../
This new syntax does not apply to static extended filters.
This commit is a rewrite of the static filtering parser into a
tree-based data structure, for easier maintenance and better
abstraction of parsed filters.
This simplifies greatly syntax coloring of filters and also
simplify extending filter syntax.
The minimum version of Chromium-based browsers has been raised
to version 73 because of usage of String.matchAll().

Cosmetic filters with unknown plain CSS pseudo-classes or
unknown plain CSS pseudo-elements will be rejected, except
for pseudo-classes/pseudo-elements which start with a `-`.

Additionally, added the keyboard shortcuts to reload the current
tab to the logger. This changes the prior behavior of reloading
the logger content itself.

The new option is `to=` and the value is a list of domain list with
similar syntax as `domain=` option. Entity-based syntax is supported,
and also negated hostname.
The main motivation is to give uBO's static network filtering engine
with an equivalent of DNR's `requestDomains` and `excludedRequestDomains`.
Essentially `to=` is a superset of `denyallow=`, but for now I decided
against deprecating `denyallow=`, which still does not support entity-
based syntax and for which negated domains are not allowed.
This commit also introduces the `from=` option, which is just an alias
for the `domain=` option. The logger will render network filters using
the `from=` version.

The "exceptor" feature has been rewritten, with the following
changes as a result:
- The excepted filters cease to exist when closing the logger
- It's now possible to temporary except network filters
When toggling on/off a temporary exception, filter lists are now
fully reloaded. This simplified managing temporary exceptions, and
made it easy to implement temporary exception for network filters,
but this also means there might be a perceptible delay when
adding/removing temporary exceptions. At this point I consider
this an acceptable side-effect just to bring the ability to easily
create temporary exception for network filters, while this
simplified the existing temporary exception code throughout.
Bring latest changes to procedural cosmetic filtering to uBOL.

These two new pseudo selectors are _action_ operators, and thus can
only be used at the end of a selector. They both take as argument
a string or regex literal.
For `:remove-class()`, when the argument matches a class name, that
class name is removed.
For `:remove-attr()`, when the argument matches an attribute name,
that attribute is removed.
These operators are meant to replace `+js(remove-attr, ...)` and
`+js(remove-class, ...)`, which from now on are candidate for
deprecation in some future.
Once the next stable release is widespread, filter authors must use
these two new operators instead of their `+js()` counterparts.

The supported syntax is exactly as per AdGuard's documentation:
- https://kb.adguard.com/en/general/how-to-create-your-own-ad-filters#extended-css-matches-attr
Though recommended, the quotes are not mandatory in uBO if
the argument does not cause the parser to fail and if there
are no ambiguities.
Additionally, improved the code to better unquote pseudo-operator
arguments, and to bring it closer to how AdGuard does it as per
documentation. When using quotes, `"` and `\` should be escaped
to preserve these characters in the unquoted version of the
argument.
Additionally, it is now possible to have `:has-text()` match the
empty string by just quoting the empty string:
...##foo:has-text("")

Some CSS4-based selectors are not supported in older browser versions
and this may cause cosmetic filtering to be wholly broken as a result.
The commit here is to isolate generic cosmetic filters from specific
ones in stylesheets such that unsupported CSS4 selectors in generic
cosmetic filters do not cause wholly breakage of cosmetic filtering
on all sites.
`uDom` is old and crusty and `dom` is meant as replacement. The
goal of `dom` is to be simpler and mainly just convenience
methods for handling the DOM with vanilla JS -- this is not a
framework.
Additionally, removed keyboard shortcuts pane which was useful
only on very old versions of Firefox.
