Subject: - Applied use of structure regen_data for a unified regen module.
 Natural and skill-heal is handled by this structure, while sitting-skill-heal
 is still player dependant (mostly because the other object types can't sit) -
 Added SCB_REGEN constant to identify status changes which alter regeneration
 - Modified SC_REGENERATION so that if val4 is set, the status actually blocks
 regen rather than increase it, this is what now Frenzy uses instead of
 "canregen_tick" - Cleaned up the status calc code for homun by moving it from
 status_calc_bl_sub_homun to status_calc_homun (where it should had always
 been) - Moved the Fleet watk code to status_calc_watk where it belongs.
