+ Updated BlockID - look for yourself * Improved button, repeater, lever, and comparator code -> simplification and splitting of some stuff from the redstone simulator file * Fixed buttons not breaking when in an invalid game state * Fixed QueueSetBlock -> improved (AGAIN) piston code + Rewrote redstone simulator Fixes: #57, #58, #205, and part of #131. Fixes FS issues: 281, 116, and 102
