Multiple non-conflicting mods

[Bobingabout]

i have a few other things that would make things easier. for this, and other things.

1. do to audio.bag what was done to ra2md.csf. allow multiple small .bag and .idx files, that include only your new files, and can be placed in mix files, such as expandmd##.mix

2. allow placing taunts in a mix file, these overide existing, or add new taunts. maybe a spacificly named taunts.mix file that can be placed inside other mix files, such as expandmd##.mix
