Refactored heuristics to collate set of origin-related
filter units are collated into a hostname trie, and
for better reuse of existing classes.
Generalized pre-test idea for bucket of filters, such
that in addition to origin-related filter units, there is
now a class to collate regex-based pattern-related units
into a new pre-test bucket class, FilterBucketIfRegexHits,
in order to test with a single regex test whether there is
a chance of a hit in the underlying bucket of filters.
Instances of these are rare, but at time of commit I found
this occurs with AdGuard France filter list.
Fine-tuned the "SNFE: Dump" output -- this new ability to
see the internal details of the SNFE has been really key
into finding/fixing issues during refactoring.
As was done with generic pattern-based filters, the source
string of regex-based filters is now stored into the
bidi-trie (pattern) buffer.
Additionally, added a new "dev tools" page to more
conveniently peer into uBO's internals at run time, without
having to do so from the browser's dev console -- something
which has become more difficult with the use of JS modules.
The new page can be launched from the Support pane through
the "More" button in the troubleshooting section.
The benchmark button in the About pane has been moved to this
new "dev tools" page.
The new "dev tools" page is for development purpose only,
do not open issues about it.
There are currently over 160 patterns with such pointless
trailing `*^` in uBO's filter lists, which ended up being
compiled as generic pattern filters (i.e. regex-based
internally), while the trailing `*^` accomplishes nothing
since it will always match the end of a URL ( `^` can
also match the end of URL).
This commit discards pointless trailing `*^` in patterns,
thus allowing most of those filters to be compiled as
plain pattern filters.
The syntax highlighter will reflect that a trailing
`*^` is pointless.
Rearrange logic to instantiate and add `important` filters
to the block realm when compiled lists are loaded instead
of when lists are compiled.
Additionally, removed now unused properties following
commit 68e14793cc.

As per internal discussion with team, best to have a simpler
scriplet, and which is hard-coded to work only on a specific
set of domains -- only those seen used by BAB.
