BATTLE.BIN : Spread Move to South Preset
-------------------------------------------------------------------------------------------------------
Parameters : Nothing

Returns : Nothing

Set some data in Scratch Pad at 0x1f800180) (refered as 0x180)
Used to Spread pathfinding around a tile (4 different routines)
    - Set Spreading Tile X and Y
    - Set Entry and Exit sides slope mod
Note : The slope mod will be used to shift slope type so the wanted side (entry or exit) flags will be 0x1 and 0x2
       This value will be used to multiply the halves to get the Side Effective height (see Slope Type)
         0x00 (low side) --> No halves
         0x01 (egde) --> Halves * 1
         0x11 (High side) --> Halves * 2
