Compacter

This mods adds a single simple block - the Compacter.

It will try crafting input items in either 2x2 or 3x3 pattern (configurable in the GUI) and output the result.
It will process unlimited items per tick, as long as there enough items and energy provided.
You can set it to work only when redstone signal is applied (configurable in the GUI).
Recursive compacting mode can be enabled from the GUI which will try combining outputed items again (for e.g. compressed cobble).
The compacter will use RF or EU power for every operation.
