BATTLE.BIN : Set Reachable Tiles
---------------------------------------------------------------------------------
Parameters : r4 - Acting Unit ID (or his mount)
Returns : r2 = Reachable Tiles counter
r2 = -0x01 if Invalid Unit
Spread Movement on Tiles
Once it's done :
- All reachable tiles flag 0x20 is enabled on byte 0x05 (8018f8cc)
- 8018f510 = 0x01
- 8018f514 = Active Unit ID
