Massive Game-level update (Work In Progress):
+ Plant model in-game.
+ Back face culling fix.
= GUI/Game World PIPE under construction.
= AddObject.java modification (+uniqueID).
+ AbstractGameObject and Interface (for uniqueID).
+ RemoveObject.

Sorry this took so long but all the things we need to add/modify started to snowball. This is an INCOMPLETE commit! I'm in the middle of working on these things and I have a lot more to add but I need to sleep and wont be able to continue working until very late tomorrow (Nov, 28). The program runs without errors (only noticeable change should be the added plants).
