-Ported the documentation for .MMV to ImportMMV in the form of comments. I think this makes things a lot simpler, and adding these comments before coding might be a good approach for future importers. That way, I merely need to understand what needs to be done and fill in the blanks.
-Added RemoveNull to get rid of the null characters in the author and game names for .MMV. -Formatted the MD5 for .MMV. TODO: -Write ImportFMV. I think I understand how these formats work well enough to try this now.
