Spelling fix for a button only admins ever see.
This 10x increases the size of admin-uploadable sound .ogg files and MIDI (10MB Midi, a scary thought). Should be big enough for any space assholes. Players can always opt out of uploaded music being downloaded and played with their "Hear/Silence-Midis" verb.
Fixes a slip-up division thing.

Misc: Bumped up admin sound file size limit, and fixed a 'tratiors' misspelling.
