browser.storage.local is now used to store non-critical
local settings.
These settings are all collated under the key
`localStorage`, and vAPI.localStorage is an API to
handle access to these values stored under this key.
vAPI.localStorage.getItem() is still synchronous but
its purpose is to return internally cached values --
this minimizes code changes throughout uBO.
Hostnames which have unpunycoded IDN or canonical
name information will have this information reported
as an extra line under the hostname name in the popup
panel, rather than as a tooltip.
For the fenix UI flavor, the save/revert tools are
now shown regardless of whether the overview area is
visible or not.
The toolip of a canonical name entry (blue)
in the popup panel will provide the alias
hostname related to the canonical hostname
in order to help with rule-making decisions.
First draft of changes as discussed with Firefox
Preview people.
In order to allow testing/evaluating these changes,
the new advanced setting `uiFlavor` has been added.
Default to `unset`; and can currently only be set
to `fenix`.
The new setting takes effect at launch only. This
new setting is not to be mentioned in official
documentation for now.
This is ongoing work, not open to external feedback.
