Compressed Blocks

Compressed blocks is mod made by me for STApi 2.0.
This mod adds compressing for blocks. Extra Utilities inspired me to create this mod for beta 1.7.3 using StAPI PRE-2.
Right now it adds only some blocks with 3 stages of compressing with crafting and uncrafting.
And maybe somewhere in future i'll port that mod to other versions like alpha and old releases (before r1.2.5).
