*Implement spell casting on transports (no more out of range error, etc)

*Add MO transports to ObjectAccessor storage
*Add functions Position::RelocateOffset and Position::GetPositionOffsetTo to help offset manipulations - BIG thanks to azazelkon for creating formulas!
*Add function to output debug info for MovementInfo and SpellCastTargets
*Throw ByteBufferException on incorrect packGUID read
*Add rfinish function to finish bytebuffer read.
