Tidying

Moved the sendLaserPacket function into its own abstract class (had to
extend WarpChunkTE for mining laser and things)
Made beamFX debug messages much more concise.
Tidied up cloaking field callMethods to use new toInt functions.
Made laser lift try to move stuff every 8 ticks rather than every 40 to
eliminate the slow feeling.
Made a custom laser calling function in laserLift since source and dest
are the same in nearly every call.
Made BeamFX only use the grey texture since it can just colorise it.
Changed a few System.out.printlns to WarpDrive.debugPrints.
