This patch adds the universal ammo system like in hyper metroid

You can customize how much ammo supers and pbs give you when picking up the item, and how much they will consume when firing them
You can edit a tile from the hud gfx to have a symbol in between the current ammo counter and the maximum ammo counter

More info in the file itself
*update: now takes SBA's and crystal flash into account, and they're customizable
*Update2:
-optimized some stuff
-added a second optional version which also features an ammo tank PLM, just like in super metroid subversion

Enjoy! (and credit ofc)
