[CGMZ] Item Categories - Version Alpha R4

Hi all, today this plugin was updated to version AlphaR4!

This version adds the ability to select from multiple item categories at once in both the Select Item plugin command and in the battle commands. If you have multiple Key categories, for example, you may want some doors to allow all keys while others only allow ice keys to be selectable. Similarly, in battle you may want all consumables to be selectable in one command, but they may have categories ingredients, seeds, etc. You can now accomplish both of these.

This was added in a backwards compatible way, so your existing commands should function as before.

• Added multi-category select to plugin command
• Added multi-category select to battle commands
