Added SuperWeapon class for Titan superweapons.  This class will handle all 4 titan superweapons, selecting appropriate effectIDs and such.
Added a whole host of effectIDs to packet_types.h, which include those needed for superweapons.
Still more work needed to fully implement the restrictions and necessities of the superweapons, but the FX show up for all clients and damage is dealt upon activation.
