Added RC's Phantom Slot System

And replaced BC's Advanced Slot System in Advanced Crafting Tables,
Emerald Pipes and Diamond Pipes.

The advantages of the Phantom Slot System is that it uses the same
Mojang code for net sync that normal Slots do. This results in much
simpler code and the slots can be treated just like any other inventory
slot instead of all the special case code that Advanced Slot does.

The Advanced Slot System is still used in several places (Assembly
Tables, Refineries, etc...), Gates but in these cases the Slot often
contains non-ItemStacks. So I'm not going to touch them for the moment.

Additionally, I cleaned up the names of some of the classes in the
Silicon package.
