Completely got rid of Tautulli and now use Plex webhooks.
Added values/variables for plextoken, plexserver, and webhookport.
Rewrote webhook handling to use flask.
Cleaned up some of the environmental variables and added the ability to not generate subtitles if the file has an internal sub of the language you want. This has to be set in SKIPIFINTERNALSUBLANG with a 3 letter code, IE "SKIPIFINTERNALSUBLANG=eng" (https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes).
Script will now default to values listed in the readme (frontpage)
