Daniel Gibson 72edf1c720 Commented out unused functions and variables 
many unused functions and variables are now commented out

You'll still get tons of warnings, which should mostly fall in one of
the following categories:
1. Unnecessary variables or values generated from .es scripts
2. Pointers assigned to from functions with side-effects: DO NOT REMOVE!
   Like CEntity *penNew = CreateEntity_t(...); - even if penNew isn't
   used, CreateEntity() must be called there!
