fixed Glass Hammering consuming 40x more energy than intended
Fixed Hammer recipes that (presumably unintentionally) had 10EUt, 16
ticks instead of 16EUt, 10 ticks.
Renamed Dense Bricks -> Firebricks
Added a new Casing for the Bricked Blast Furnace, GT_Block_Casings4, ID
15
Refactored the non-electric Blast Furnaces:
The Bronze Blast Furnace and the Bricked Blast Furnace extend a
superclass to ensure consistent behavior.
Subclasses only differ in texture, description, and Casing Block.
