Performance and other improvements

Tested it with 20 players using the oculus as the server, seemed to work OK. Remove the child network transforms from the rocks, rockets and shots, improved performance immensely. May have introduced an issue where clients do not follow the host to the next level, need to determine if this a real issue or just something due to mismatched versions between oculus and PC. The host is now always a white rocket so you can tell who should not quit the game and stop the game for everyone else. Better color selector code so everyone is a somewhat different color, probably doesn't do too well when there are 20 players however. Player shots will not destroy their own ships, this was an issue with clients as their shots were delayed getting their position back from the server and players could run into their own shots while shooting at high speed. May want to make the shots the same color as the ships in the future.
