Extra Enemy Drops

#Extra Enemy Drops v1.0
#----------#
#Features: Let's you set, via notes, more than just three item drops
#           from an enemy. Yay!
#
#Usage:    Plug and play, customize as needed
#
#         Enemy Notetags:
#          <DROP type id rate>
#           type is 1 for item, 2 for weapon, 3 for armor
#           id is the id of the item
#           rate is the 1/rate of the item, 20 would be 1/20 chance
#
#          A weapon of id 3 that drops 1 out of 5 times would be:
#           <DROP 2 3 5>
