Core/PhaseMgr: Implemented Phase Definitions, Terrainswap and multiphasing

* fixes cataclysm aura effect SPELL_AURA_PHASE without phasemasks defined in miscValueA
* implements CONDITION_SOURCE_TYPE_PHASE_DEFINITION

Thanks to:
 - Cyberbrest: For the hard research work about multiphasing.
 - Venugh: He helped me with a lot of strange compile Errors.
 - Shauren: For the 4.3.4 phaseshift packet.
 - Booksize: He showed me how terrainswap works
