-Fixed another PEBCAK error preventing client units from being destroyed.

-Added the rest of the client units so multiplayer no longer crashes when the first fighter is created (most don't do anything yet)

-Client structures are now actual objects instead of just being drawn (this will make client targeting logic and other things much easier)

-Clients no longer run code which causes their match to end immediately (this also keeps them from improperly unlocking 3 related achievements)

-Movement of host player's mechbots now registers for clients...though rather imprecisely.
