BATTLE.BIN : Check if Status Should/Can be Added
 +
------------------------------------------------------------------------------------------
 +
Parameters - r4 : Clockticks left before Acting Unit next turn
 +
              r5 : Considered Unit data pointer (potential target)
 +
              r6 : Status ID
 +
 +
Returns r2 : 0x00 if status not inflicted yet
 +
              0x00 if status is inflicted but will fade before next turn
 +
              0x00 if considered unit is jumping and will land before next turn
 +
              0x01 if Unit is Jumping and will land later
 +
              0x01 if considered status is innate
 +
              0x01 if considered status is inflicted do not have a CT
 +
              0x01 if considered status is inflicted but won't fade before next turn
 +
  --> r2 = 0x00 if worth to be inflicted

Parameters - r4 : Clockticks left before Acting Unit next turn

             r6 : Status ID

Returns r2 : 0x00 if status not inflicted yet
             0x00 if status is inflicted but will fade before next turn
             0x00 if considered unit is jumping and will land before next turn
