+ Moved all simulator data into individual chunks
* Cleaned up parameters for functions and some code
* Fixed repeaters powering off faster than they power on
The main issue before was that, although the redstone simulator stored
blocks to be simulated in individual cChunks, other data, such as
powered lists, and etcetera, were global regardless of which chunk was
being simulated. Therefore, with worlds with lots of redstone, each tick
saw the ticking of chunks, which themselves iterated through the entire
dataset needlessly, creating LOTS of lag. Should be better now :)
