Parameters : r4 = Acting unit's data pointer
Returns : r2 = 0x00 if Action can be taken
r2 = 0x08 if Unit is in deep water
r2 = 0x07 if unit can't act
r2 = 0x05 if unit is a frog attempting to do non frog things
r2 = 0x03 if unit does not have enough MP (And action menu = default)
r2 = 0x02 if unit is silenced and [Action menu = default or monster] and [Ability is silencable]
If action menu = default : Store MP used/cost at 0x801938eb (Check Half MP too)
