The idea is to remove as many dependencies as possible for
low-level ScriptletFilteringEngine in order to make it easier
to reuse the module outside uBO itself.
The high-level derived class takes care of caching and
injection of scriptlets into documents, which requires
more knowledge about the environment in which scriptlets
are to be used.
Also improve scriptlet cache usage to minimize overhead of
retrieving scriptlets.

Changes:
Use browser.alarms to trigger selfie creation. Presence of a selfie
improve markedly time to readiness when uBO is unsuspended.
Mirror content of storage.local to (in-memory) storage.session for
faster load to readiness when uBO is ususpended.

The `randomize` paramater introduced in https://github.com/gorhill/uBlock/commit/418087de9c
is now named `directive`, and beside the `true` value which is meant
to respond with a random 10-character string, it can now take the
following value:
war:[web_accessible_resource name]
In order to mock the XHR response with a web accessible resource. For
example:
piquark6046.github.io##+js(no-xhr-if, adsbygoogle.js, war:googlesyndication_adsbygoogle.js)
Will cause the XHR performed by the webpage to resolve to the content
of `/web_accessible_resources/googlesyndication_adsbygoogle.js`.
Should the resource not exist, the empty string will be returned.
Also added additional safeguard against sticky unprocessed-request
status: all unprocessed-request statuses will be cleared after a
minute elapsed following intialization. The idea is that if the
user hasn't care to force a reload of the page, then it's assumed
to be by choice and uBO should stop informing about the status.
uBO will now verify that at least one unprocessed network requests
at launch should have been blocked in order to warn users of
unprocessed network requests through the `!` toolbar icon badge.
For example, with default filter lists, there is nothing to block
on `wikipedia.org`, and hence in this case it's not useful to
present the user with the `!` badge.
Therefore uBO will not show the badge *only* when at least one
unprocessed network requests should have been blocked had uBO been
ready when it was fired by the browser.

The incomplete filtering status of a given tab at browser launch
will be carried over visually as a yellowish `!` badge until the
web page in the tab is force reloaded, navigated away, or closed.
The purpose is to make it obvious to end users that a web page
has not been filtered properly and to avoid issue reports
related to this.
It is expected that Firefox should never be affected by cases of
yellowish badge -- that is unless the setting "Suspend network
activity [...]" has been disabled, in which case the new behavior
will also be useful to those who disabled the setting.

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.

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.
