Picture Axe

Added LIT functionality to the Six Sided Image Blocks.
Added Six Sided Image Block cloning.
(When a stick is in the offhand and six sided image blocks are in the main hand by sneak right-clicking you can bulk remove glowstone)
(You can clone images from one image blocks onto another by simply putting the source (1 stack, the one you will be copying from) and the target (the one which will take the images from the source)).
(You can bulk apply glowstone to image blocks by putting glowstone in the crafting grid next to the image blocks)
