Let the rewrite begin

Using a hybrid of the old logic and wisthy's master logic in order to
tighten the master-servant connections
Moved Repo to common, renamed to TSRepo
Created NBTNames subclass for TSRepo to store NBT names
Implemented TCon's master/servant interfaces directly into Steelworks
for better control
Added IRedstonePowered interface for common switch-flipping operations
More refactoring/cleanup of DeepTankLogic in regards to previous commit

WORK IN PROGRESS! Things will not work, yet!
