This includes the following changes (mostly related to the above):
- Move loc_compare functor to location.hpp
- Add reattach() function to rebind a town or outdoor section to a different scenario object. (I don't think this is strictly necessary, as the scenario reference is only used in limited situations in the game itself, not in the editor, but it's better not to keep a reference to freed memory around when importing a town or sector from another scenario, even if the reference is never accessed.)
- Fix imported towns not being officially "loaded" until you explicitly use Load a New Town to reload them
- Fix Choose button in Load New Sector dialog
- More functions in the vector2d implementation
- You now specify your name instead of the scenario filename in the first dialog
- A file dialog pops up after the second dialog, to let you choose the filename and location
- Fixed using Warrior's Grove even if you chose not to
- Fixed not recognizing .EXS as a valid legacy-scenario extension and appending .boes, resulting in .EXS.boes
- Adjust Difficulty scenario flag set on by default
- Fix attempt at accessing invalid placed town locations
- Fix attempt at accessing invalid terrain in editor when checking whether to apply transformations
- On load, the game now detects graphic sheets and sounds whose IDs are "discontinuous", as well as graphics intended to directly replace preset graphic sheets.
- Edit sheets dialog can now handle "discontinuous" graphics. (The edit sounds dialog already could.)
- Edit sheets dialog prompts user to create a new sheet if there are none already, and also if there are some but not ID 0 (in the latter case they can cancel and still edit the sheets).
- Edit sheets dialog prompts user to convert sheets if the scenario is legacy, rather than doing it silently
- Edit sheets dialog now has "new" and "delete" buttons
- Edit sounds dialog now has functioning "delete" button
