Remove the arbitrary limits on the following quantities:

- Number of terrain types - as long as the last terrain in the list is unused, you can delete it
- Number of monster types - as long as the last monster in the list is unused, you can delete it
- Number of item types - as long as the last item in the list is unused, you can delete it
- Number of special items
- Number of strings (scenario, journal, outdoors, town)
- Number of signs (outdoors, town)
- Number of description rectangles (outdoors, town)
- Number of town entrances (outdoors)
- Number of dialog nodes (town); number of personalities per town is still limited, but since you can use personalities from any town and the number of towns is unlimited, you still have effectively unlimited personalities

Other related stuff:
- Fix ability to select nonexistent terrains/items/monsters from the palette
- Fix inability to find unused special strings in some cases
- Fix sometimes incorrectly selecting the current node as the next node in the chain, instead of a new node
- When cancelling from the special node dialog, it's a bit more intelligent about whether or not to drop nodes from the end of the list
- Edit string dialog now has a cancel button
- Save otherwise unused talk nodes if they contain strings, to avoid loss of data that might be important
- Fix scenario and journal strings loading incorrectly if some strings were blank
- Fix some issues with list modes activated by menu not appearing until the mouse moves over the window
- Fix incorrect instructions in list modes (it's alt-click, not command-click as the instructions indicated)
- Implement "erase town entrance" button and create a visual difference between town entrances with an assigned town and those without
- Fix inability to erase monsters after the first 60 in town
- Fix escape key accepting changes in the shop dialog, instead of cancelling
- Fix quest/shop list resetting to top after editing one
