-Fixed the infinite loop caused by Movie.FixMnemonic. That was dumb.

-Removed the FCEUX handling from SubtitleList.AddSubtitle; it didn't work at all, which is good because we no longer support FM2 natively anyway!
-Added MovieImport.AddSubtitle, which parses FM2 subtitles and forwards them to the .TAS movie object.
--For the color, I used 16777215 as it seems the subtitles use decimal instead of hexadecimal...why?
--Even though I used this color, which is definitely the equivalent of FFFFFF (white), the subtitles show up as black. I don't think this has anything to do with the importer, but it's worth looking into.
