/*
All form changes are checked for the base species!
Putting a form change on a form has no effect

FORM_ITEM_USE:
    Changes any pokemon with a matching base species (even if
    it is a form) to the target species. 
    param1 = item to use
    param1 = ability to check for (none means any)

FORM_ITEM_HOLD:
    param1 = item to hold
    param2 = ability to check for (none means any)

FORM_MOVE:
    param1 = move to check for
    param2 = true if form change activates when move is forgotten,
             false if form change activates when move is learned

FORM_WITHDRAW:
    Form change activates when the Pokemon is withdrawn from the PC or Daycare.
    no parameters
