Autocombination multiple item loss fix

Getting multiple spell items at the same time will no longer
accidentally delete some of the items.
Spell Item Splitters, graphical upgrade, M&M scrolls

Joguer now sells empty bottles, blank scrolls, and uncharged wands.
These items can be used to split stacked spell items in half.

Joguer also sells Mirth and Melancholy scrolls that work exactly as you
might think.

Finally, all scrolls now have a stamp that reflects their spell school.
(there were 9 hidden unused scroll graphics)
