Add local server entity id fix

[MESLewis]

This fix allows 2No2Name's wireless redstone to work 100% reliably in single player. It (somewhat hackily) separates the entity id counter for server entities from the counter for renderer entities.

I'm fairly confident there is a better way to accomplish this, feedback greatly appreciated

If you make a pull request for carpet-fixes, ill add it. ;)
