9/6 Update: Major Performance Improvements

This is a small but very significant update.   Major performance improvement, to the point where the lag (especially in browser) should be minimal.  

*  Removed Character HUD from NPC's and cave enemies, which immensely increases frame rate.  

*  Made changes to how the cave lights work, so they're only used on the maps they're intended for (this also increased performance a bit).

*  Fixed a bug in Fire Cave which wouldn't let you enter it properly.

*  Set minimum and maximum frame rates (30 and 60 respectively), the game should run at 60ish at all times now.
