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
