Optimization of table allocation, more sophisticated entity damage (#37)

Browse Source 
This pass cleans up a lot of unnecessary table allocation and disposal, which should help with memory usage and garbage collection.

It also adds some sophistication to the entity damage process from diggers, allowing items to be picked up into Digtron inventory.
