* Add ability to configure site alts w/ env vars
Site alternatives (i.e. twitter.com -> nitter.net) can now be configured
using environment variables:
WHOOGLE_ALT_TW='nitter.net' # twitter alt
WHOOGLE_ALT_YT='invidio.us' # youtube alt
WHOOGLE_ALT_IG='bibliogram.art/u' # instagram alt
Updated testing to confirm results have been modified.
* Add site alt vars to docker settings and readme
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.
