Fixed some memory leaks...

So There were some memory leaks that decided to come out of hiding a few days ago, they corrupted the skysphere's vertex info and slowed down the engine and many other nasty things. So I spent all day today hunting them down, i found the largest leaks and plugged them up but there are still 2 that  elude me, both of which are always present even if i make the main function simply return immediately. so the leaks probably reside in a library that's being loaded. maybe i compiled Bullet wrong? IDK but they don't seem to affect the gameplay so i am forgetting about them for now, they are small anyways only a total of 2130 bytes.
