- Fix targeting falsely complaining about being off the edge of town
- Monster info dialog works properly; attacks now display correctly
- Fix dialogs always showing the wrong terrain or monster graphic
- Spell menus, monster menus, and PC editor item menus all work
- Spellcasting dialog now chooses the correct spell
- Fix out-of-place LED in spellcasting dialog
