New policy setting: `rulesets`
Type: array
Type of array items: string
Each item in the list is a list id (as seen in `rulesets/ruleset-details.json`),
prefixed with either `+` to enable the ruleset, or `-` to disable the ruleset.
Users will not be able to enable or disable rulesets present in the `rulesets`
policy. Disabled rulesets will not appear in the dashboard.
Use `-*` to remove all non-default rulesets, except for those added
using `+[ruleset_id]`.
Additionally, some work has been done to properly handle policy changes in
a non-blocking and deferred manner, as I observed that it often takes long
for calls to `storage.manage.get` to resolve. This potentailly takes care
of the following issue:

See `managed_storage.json` for available settings. Currently
only `noFiltering` setting is availale.
`noFiltering` is an array of strings, each being a domain for
which no filtering should occur.

Avoid using updateContentScripts() as it suffers from an unexpected
behavior, causing injected content scripts to lose proper order
at injection time. The order in which content scripts are injected
is key for uBOL content scripts. Potential out of order injection
was causing cosmetic filtering to be broken.
Use actual storage API to persist data across service worker
wake-ups and browser launches. uBOL was trying to avoid using
storage API, at the cost of somewhat hacky code (using DNR API
to persist settings).
Make use of session storage if available, to speed up
initialization of waking up the service worker (which at this
point is necessary to properly implement cosmetic filtering).
Specifically, avoid long list of hostnames for the `matches`
property[1] when registering the content scripts, as this was causing
whole browser freeze for long seconds in Chromium-based browsers
(reason unknown).
The content scripts themselves will sort out which cosmetic filters to
apply on which websites.
This change makes it now possible to support annoyances-related lists,
and thus two lists have been added:
- EasyList -- Annoyances
- EasyList -- Cookies

These annoyances-related lists contains many thousands of specific
cosmetic filters and as a result, before the above change this was
causing long seconds of whole browser freeze when simply modifying
the blocking mode of a specific site via the slider in the popup
panel.
It is now virtually instantaneous, at the cost of injecting larger
cosmetic filtering-related content scripts (which typically should
be garbage-collected within single-digit milliseconds).
Also, added support for entity-based cosmetic filters. (They were
previously discarded).

`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.
Network filters with csp= option will now be enforced.
Caveat: DNR API does not have support for exception csp= rules,
so excepted csp= filters are currently rejected at conversion time.
This adds support for `redirect=` filters. As with `removeparam=`
filters, `redirect=` filters can only be enforced when the
default filtering mode is set to Optimal or Complete, since these
filters require broad host permissions to be enforced by the DNR
engine.
`redirect-rule=` filters are not supported since there is no
corresponding DNR syntax.
Additionally, fixed the dropping of whole network filters even though
those filters are still useful despite not being completely
enforceable -- for example a filter with a single (unsupported) domain
using entity syntax in its `domain=` option should not be wholly
dropped when there are other valid domains in the list.
