Teleportation works accross dimensions
Interupting the teleport works properly now
Gui improvements: the interrupt button is only enabled is there actually is a connection and when selecting a transmitter the current receiver is automatically selected too
Added configuration section to control various parts of the teleporter.
Fixed 'Check' button so it works fine on entities in other dimensions.
Upgraded forge to 1.7.10-10.13.1.1225
