Add advanced setting to default modify webext flavor

Browse source 
Name: modifyWebextFlavor

Value: A list of space-separated tokens to be added/removed from the
computed default webext flavor.

The primary purpose is to give filter list authors the ability to
test mobile flavor on desktop computers. Though mobile versions of
web pages can be emulated using browser dev tools, it's not
possible to do so for uBO itself.

By using `+mobile` as a value for this setting will force uBO
to act as if it's being executed on a mobile device.

Important: this setting is best used in a dedicated browser
profile, as this affects how filter lists are compiled. So best
to set it in a new browser profile, then force all filter lists
to be recompiled, and use the profile in the future when there
is a need to test the specific webext flavor.
