Remove unused var.
Fix typo.
Add mappings for general elements, and for skillchain elements.
Make the elements.list an actual list.
Add a utility function for determining and setting the appropriate gorget and
belt for weaponskills. Allows setting a default value if the gorget or belt
are not available.
Added gorgets and belts to the UserGlobals file, along with vars for storing
the currently determine gorget/belt, and the default item if the gorget/belt
isn't found.
Call the utility function when creating the default weaponskill set, so that
the values of those vars are updated.
Moved add_obi to the utility file, and adjusted to be a bit more generically
useful.  Updated calls to this function.
