-Applied micro500's flag ANDing syntax to all of my functions...I concede that this is a much simpler way to do this. 

-Fixed ImportFMV's movie title; before, I mistook it for the game name.
-Made "comment" and "SyncHack" constants.
-Moved the "ControllerDefinition"s outside of all of the loops.
-ImportGMV:
--Emulation Version => Movie Version.
--Added the PAL header.
--Made it so that the 6-button error is a warning; considering that the code already properly handles the controller properly and all that needs to be done is have Bizhawk actually support that kind of input, I don't feel there's a reason to go so far as to kill the conversion in this case.
--Reformatting.
---Notably, I added a player loop to simplify the frame data.
--It seems that 1937M uses a 6-button recording and 1731M has 2-player input...bizarre. Anyway, this means that ImportGMV should be good now.

TODO: ImportVMV, ImportNMV, ImportMCM, ImportSMV, Atari core? :)
