Tabless network requests were bypassing uBO's
onBeforeRequest's listener when in suspended
mode. Suspend mode occurs during the time the
filter lists are all reloaded.
Regression from:
- 1dfdc40e09 (diff-d04c15ee6bff6a6269c6aee25a7c7522R1122)
This works only for platforms supporting the return of
Promise by network listeners, i.e. only Firefox at this
point.
When filter lists are reloaded[1], there is a small
time window in which some network requests which should
have normally been blocked are not being blocked
because the static network filtering engine may not
have yet loaded all the filters in memory
This is now addressed by suspending the network request
handler when filter lists are reloaded -- again, this
works only on supported platforms.
[1] Examples: when a filter list update session
completes; when user filters change, when
adding/removing filter lists.

The Chromium version of uBO has declared `unlimitedStorage` since the
extension was first published in 2014. Declaring this permission in
Firefox brings uBO inline with the Chromium version. I suspect some
reported errors could be caused by IndexedDB eviction due to the lack
of `unlimitedStorage` permission.
Additionally, a timeout has been added when uBO tries to access its
indexedDB storage. It's unclear whether this will help with the
mentioned related issue though, the root cause is still to be
identified.

Both flavors will be stitched together into a single
`vapi-qebrequest.js` file.
The decision of which flavor to use will be made at runtime,
according to the browser environment.
Performance-related work: the logger data has been decoupled
from the DOM -- inspired from CodeMirror's way of efficiently
handling large amout of text data.
This decoupling now makes the logger highly efficient CPU- and
memory-wise, and open the way to more possibilities.
Ability to configure some aspect of the logger behavior and
visuals:
- The hard-coded limit of 5000 entries has been
removed and is now replaced with a variety of
user-configurable settings to enforce the discarding of
logger entries.
- Some columns in the logger output can now be hidden.
The filter list look-up feature has been merged into the
existing overlay dialog used to create URL rules or static
filters, as an entry in a new "Details" pane.

The minimum version supported on Firefox has been bumped
up to 55.0.
When using paths, platform implementations of setIcon typically
will fetch the resource then convert to image data internally.
It is preferable for uBO to do this conversion itself as it can
be done only once at launch time.
With chromium-based browsers, using image data eliminate the
incessant network traffic to fetch browser icons as reported
in the extension's dev tool, meaning a good chunk of overhead
is eliminated.
Also, use optimal icon sizes, as of now both chromium and firefox
prefers 16px instead of 19px, and 32px instead of 38px.
* Fix leftovers from old code.
* change changes.procedural.size to changes.procedural.length
changes.procedural is an array so it should be changes.procedural.length
the code works with changes.procedural.size because (undefined !== 0) is always true.
