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().

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.
`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.
First iteration of adding scriptlet support. As with cosmetic
filtering, scriptlet niijection occurs only on sites for which
uBO Lite was granted extended permissions.
At the moment, only three scriptlets are supported:
- abort-current-script
- json-prune
- set-constant
More will be added in the future.
Specific plain CSS cosmetic filters are now supported.
Cosmetic filtering will occur only after the user explicitly
grant uBO extended permissions for a given site, so that it
can inject CSS on the site.
A new button in the popup panel allows a user to grant/revoke
extended permissions to/from uBO Lite for the current site.
More capabilities will be carefully added for when extended
permissions are granted on a site, so specific cosmetic
filtering through plain CSS is the first implemented capability.
Generic and procedural cosmetic filtering is not implemented.
The current implementation for plain CSS cosmetic filters is
through declarative content injection, which does not require
the service worker to be alive, the browser takes care to
inject the cosmetic filters.
However declarative CSS injection does not support user
styles, so the injected cosmetic filters are "weak". I consider
this is a browser issue, since user styles are supported by
Chromium, there is just no way in the API to specify user
styles for the injected content.
Also:
- Fixed dark theme issues
- Added Steven Black's hosts file
Keep in mind all this is very experimental and implementation
details in this release may (will) greatly change in the future.
Additionally, have a list of preset colors for the color
picker (unlike Firefox, Chromium's built-in color picker
does not have a list of preset colors by default).
