Created system to reserve sections of SyncIDs per client

This allows clients to spawn a new sync object after the level loads and synchronize it.
Changed how un-initialized sync objects are detected
Koopa shells are the first thing to use this new system

Removed network_object_settings() command, instead explicitly setting the sync object parameters
