Breaking shows preview (breaking only in creative).

Build mode cancels when opposite mouse button is pressed (left button when placing, right button when breaking).
Simple shader when placing more than 1500 blocks (or when useShaders is false).
Added axis limits in addition to total block limit.
Fixed placing on self (and being pushed).
Fixed issue #15 silk touch, shearing leaves, dropping bed etc by using Block#harvestBlock (items dont drop directly to inventory anymore).
Fixed randomizerbag not randomizing in buildmodes.
