* Adds a debug generator for ForgeEnergy.
This adds a simple debug block to test external energy injection via
ForgeEnergy and not rely solely on creative cells.
The energy has two functions. The first is acting as an infinite
ForgEnergy battery, this is unused by AE2 itself as nothing pulls
energy.
The second one is injecting energy every tick into any adjacent block
accepting ForgeEnergy.
The base generation is 8 per tick, but this is increased by the power of
adjacent TileEnergyGenerators.
