Packfile Caching has increased sector size from 4096 to 8192. Everything seems to be working... but since I have never manipulated the code's sector size. I hope this doesn't break filecaching or introduce abnormal behavior. But this should increase the max size of pakfile from 150 or so MBytes to 300.
Also fixed unloading of samples.... We were not correctly unloading them and sometimes would cause a memory leak or invalid samples to be played.
