BATTLE.BIN - Able_to_move/act_checks_(Menu%3F)
---------------------------------------------------------------------------------------
Parameter : r4 = Unit Battle ID
            r5 = Skillset ID
            r6 = Pointer to output list of Ability ID
            r7 = Pointer to output list of Ability MP cost
            Previous routine Stack Pointer is used to pass other pointers
                Stack 0x10 - Pointer to output list of Ability CT
                Stack 0x14 - Unused pointer ?
                Stack 0x18 - Pointer to output list of Ability Silence/Reflect flags
                Stack 0x1c - Pointer to output list of Nb of Turns unit resolution

Returns : r2 Nb of known and usable Abilities in skillset

This Routine will : - check known abilities in skillset, 
                    - check they can be used (sword - matera blade- Frog). 
                    - Set their CT (check short charge or non charge)
                    - Set their MP cost (checking half MP)
                    - Fill the lists
