Instead of having the `localStorage` data being accessed
from different locations, all accesses are now funnelled
to the main process.
Doing so simplifies the code in auxiliary processes and
also remove the need for browser.storage.local.onChanged()
listeners.
No longer using an onChanged() listener also happens to
remove spurious warnings from the Firefox console.

This commit focuses on implementing the use of
CSS `var(...)` throughout so as to make it easy
to create themes -- a requirement for uBO to
support a dark theme.
There is still work to do regarding converting
uBO's CSS to completely support `var(...)` but
being able to start using theming will help
complete and fine tune CSS `var(...)` support.

Roughly, the changes in this commit:
- Make it easier to implement a dark theme eventually:
- Flatten the look of buttons
- Remove the use of `opacity` style property as a
color modifier
- Some work toward removing dependency on FontAwesome
font

This commit fixes parts of the re-design not
rendering as intended as per <https://github.com/brampitoyo>'s
feedback screenshots.
The dashboard tab buttons have been converted to
`span` tags (from `a` tags), thus eliminating
the unwanted side effect of the text being
rendered as unvisited links (blueish).
The font size intended for touch screens was not
taking effect due to bad cut & paste.
Other minor adjustments to improve consistency
in spacing.
This commit add the ability to fetch from CDN servers
when an asset is fetched as a result of auto-update.
If an asset has a `cdnURLs` entry in `assets.json`,
the asset will be auto-updated using one of those
CDN URLs. When many CDN URLs are specified, those
URLs will be shuffled in order to spread the bandwidth
across all specified CDN servers. If all specified CDN
servers fail to respond, uBO will fall back to usual
`contentURLs` entry.
The `cdnURLs` are used only when an asset is
auto-updated, this ensures a user will get the more
recent available version of an asset when manually
updating.
The motivation of this new feature is to relieve
GitHub from acting as a CDN (which it is not) for
uBO -- an increasing concern with the growing adoption
of uBO along with the growing size of key uBO assets.

The changes in this commit are mostly related
to the "Filter lists" pane.
An eye icon has been added, which purpose is
to view the content of a list. Clicking on the
name of the list will toggle the list's
checkbox.

The race condition was that a content script could
query the main process to retrieve cosmetic filters
while the cosmetic filters had not been yet fully
loaded into memory. The fix ensure that an already
injected content script will re-query once the
cosmetic filters are fully loaded in memory at
browser launch time.

The problematic site does not declare the expected
`disqus_shortname` global variable, so the scriptlet
has been extended to deal with such occurrence.

Since cname-uncloaking is available only on Firefox
at the moment, the fix is relevant only to Firefox.
By default uBO will no longer cname-uncloak when it
detects that network requests are being being proxied.
This default behavior can be overriden by setting the
new advanced setting `cnameUncloakProxied` to `true`.
The new setting default to `false`, i.e. cname-uncloaking
is disabled when uBO detects that a proxy is in use.
This new advanced setting may disappear once the
following Firefox issue is fixed:

Provide a way to optionally deduplicate filter
instances, useful for filter instances with:
- high likelihood of duplication; and
- non-trivial memory footprint per instance
- For examples, filter instances to implement
`domain=`, `denyallow=`, `csp=`.
Cursory tests show this helps further reduce
uBO's memory footprint.
This concerns the static network filtering engine.

New static network filter type: `cname`
By default, network requests which are result of
resolving a canonical name are subject to filtering.
This filtering can be bypassed by creating exception
filters using the `cname` option. For example:
@@*$cname
The filter above tells the network filtering engine
to except network requests which fulfill all the
following conditions:
- network request is blocked
- network request is that of an unaliased hostname
Filter list authors are discouraged from using
exception filters of `cname` type, unless there no
other practical solution such that maintenance
burden become the greater issue. Of course, such
exception filters should be as narrow as possible,
i.e. apply to specific domain, etc.

New static network filter option: `denyallow`
The purpose of `denyallow` is bring
default-deny/allow-exceptionally ability into static
network filtering arsenal. Example of usage:
*$3p,script, \
denyallow=x.com|y.com \
domain=a.com|b.com
The above filter tells the network filtering engine that
when the context is `a.com` or `b.com`, block all
3rd-party scripts except those from `x.com` and `y.com`.
Essentially, the new `denyallow` option makes it easier
to implement default-deny/allow-exceptionally in static
filter lists, whereas before this had to be done with
unwieldy regular expressions[1], or through the mix of
broadly blocking filters along with exception filters[2].
