Tear out most of the legacy code in the scenario editor - see below for details

- All Carbon code is gone
- Many dialogs converted; some are still left unimplemented since they still need to be converted
- Menus converted to a xib file
- The giant arrays specifying the configuration of the special node dialog for each special node type have been replaced with maps and sets.

Changes to dialogs:
- pict choice dialog can now show picts of differing types; this was required for picking a monster graphic, as monsters of all sizes need to be shown in the same dialog
- string choice dialog can set the title, and properly shows the currently selected string
- LEDs now accept font format
- Fixed LED group's calculation of its rect
- Fixed LED group crashing if it has no selection
- Tabbing between text fields now works
- Fix display of larger monster graphics in dialogs
- Fix the script element content showing in the browser preview
