The invidious instance has been updated to invidious.snopyta.org, since
this instance is more reliable and has more users according to
instances.invidio.us
All site alternative redirects now redirect without the 'www' subdomain,
since most of the alternative sites don't have this subdomain set up.
Improves clarity of the meaning behind the "Country" filter -- Google
seemingly uses this value to only return results that are hosted in a
particular country, as evidenced in the search differences highlighted
in #123. It now mentions that the results are filtered by website
hosting location.
Also, now that invidio.us is shut down, the fallback URL (invidiou.site)
is now used instead.
Full implementation of social media alt redirects (twitter/youtube/instagram -> nitter/invidious/bibliogram) depending on configuration.
Verbatim search and option to ignore search autocorrect are now supported as well.
Also cleaned up the javascript side of whoogle config so that it now
uses arrays of available fields for parsing config values instead of manually assigning each
one to a variable.
This doesn't include support for Google Maps -> Open Street Maps, that
seems a bit more involved than the social media redirects were, so it
should likely be a separate effort.
