Added new AI/announcer sound files for when events happen, when game starts or ends, when shuttle is called/recalled/docks and when a new AI is chosen.
Removed traitor.ogg and main.ogg because they weren't being used and were quite large files.
Fixed flash effect and crit-state effect. But now shroom effect is a bit broken. (to-do)
Added a sound effect when a robot comes to life.
