+ 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 :)
Changed the signitures of the following to use interfaces:
GetPlacementBlockTypeMeta
OnPlaced
OnPlacedByPlayer
OnDestroyed
OnNeighbourChanged
NeighbourChanged
OnUse
CanBeAt
Check
If a coordinate was queued, and then the block there was broken, it
would reappear: double items!
Also now just sets meta if previous and current blocktypes matched.
