few additions and bug fixes

Added Hand Sway (not an option yet) from b1,8

Fire works properly in multiplayer now and also renders on undead mobs in sunlight now

hopefully fixed bow stuck bug on touchscreen devices

Fire on entites uses updated rendering from b1.6.6

Shadow bug fix attempt the 15th

Added looking at block in debug screen

Zombie Pigman now renders his hat layer

Temporarily disabled most randomlevelsource cave, canyon and tall grass code just for this commit to test performance
