- Generalized the special queue which was formerly used only for town enter/leave specials, and made the see monster special also use it.

- Redid the draw items and draw fields code to draw just on one space rather than the entire area.
- Fixed bug where special spots were not masked properly.
- Removed some large chunks of commented, obsolete code.
- Found and fixed bug where the instant help system caused the game to believe you had stolen items when in fact you hadn't.
- Added enum for special node context (ie the context in which a special node is being run); not really used yet though.
- Added support and graphic for forcecage, and graphic for stone block; mechanics not yet implemented.
