Brave Search and Keyword per semanticdata

Adds Brave Search to Firefox and includes @brave, !brave, @b, and !b as search keywords. This allows you to easily search brave in multiple new ways. Example: [!b !w Hello World] would let you search Wikipedia directly from any website, regardless of whether you set Brave as your main search provider.

After much trying, I am unable to make this extension work for Firefox on Android. The limitations placed by Mozilla makes chrome_settings_overrides inaccessible for Android, which is necessary to assign a new search engine under that platform.
