Consider adding .txt extension support for subtitle files
Totem does not support auto-loading subtitles from files with .txt extension. These subtitles work when loaded manually, but they aren't auto-loaded as Totem limits the list of extensions for auto-loaded files to the following: sub,srt,smi,ssa,ass,asc. The extension .txt is quite popular on many Internet sites with subtitles, also all hardware players that support playing of video files with external subtitles support this extension, so one may often stumble upon already burnt CD-Rs or DVD-Rs containing movies with subtitles with .txt extension. It would be easier if Totem could auto-load them.
