KH2: New Unit Test and better keyblade fill (#1744)

__init__:
 - Added exception for if the player has too many excluded abilities on keyblades.
 - Fixed Action Abilities only on keyblades from breaking.
 - Added proper support for ability quantity's instead of 1 of the ability 
 - Moved filling the localitems slot data to init instead of generate_output so I could easily unit test it

TestSlotData:
- Checks if the "localItems" part of slot data is filled. This is used for keeping track of local items and making sure nothing dupes
