Multitileentity precursor (#963)

* Refactors
* Refactor CoverableTileEntity a bit more, pull out a CommonMetaTileEntity
* Add an IDebugableTileEntity interface instead of checking various subclasses
* Move more redstone related things  to CoverableTileEntity
* Add IGTENet

* Final and dead code removal

* Address a few comments, fix a few comments, remove some more dead code, and add some more finals.

* fix bad rebase
