#_/  Adds a function to the Skills screen which allows the player to display
#_/  skillss by catagory.
#_/  To assign a category to an skill, you must add <category IDENTIFIER> to the
#_/  notes on the specified item.
#_/  EX. Fire would be listed as <category Offensive Magic> and Dual Strike
#_/  listed as <category Offensive Skills>, provided you use the default
#_/  terminology. Parts of this script are untested, however it should work as
#_/  it is just fine. Areas untested will be highlighted by comments.
