View source for Current Action Data Nulling

 Need r4 = Unit data pointer 
 Reset most of unit action data from 0x00 to 0x29   --> See [[Data/Table_Locations#Current Action Data|Current Action Data]]
 Preserve : - Current action reaction ID (halfword at +0x0e)
            - Last attack recieved ID (halfword at +0x26)
 Set hit% to 100% and hit flag to "hit"
