qutebrowser: Refactor gemini userscript
Now possibly a little less clunky (though still using soon-to-be deprecated modules), and able to correctly surf gemini/non-gemini pages as a userscript or as a stand-alone script (simply calling it from command line). Works as before for tabbed pages (the clunky rename/symlink way). Can now also be used as the default way to surf to links so I switched out my qutebrowser f/F link hinting for this script. Will simply open links if staying on http but open gemini version as local file if moving on to gemini. Could probably be rewritten as an actual plugin to interject itself in link opening to be a little more elegant (similar to the redirect code I have running to move to open source web frontends).
