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
- Introduce enum for step sounds
- Remove union for treating terrain flags as either signed or unsigned
Editor:
- Add Choose button to select the "transform to" terrain.
- Implement Choose buttons as appropriate for the terrain flags, including editing the special that a terrain calls.
- Range-check the terrain flags.
- Add Custom button to choose a town as the combat arena.
- Fix/tweak/improve several of the terrain flag prompts.
- Fix placing shortcut key in field as its ASCII code instead of the letter
- Fix some of the range checks that were already in place but were incorrect or improperly static
Game:
- The wilderness terrain types now allow specifying how many d6's of food you get when hunting there.
- Crumbling terrain uses flag 2 instead of 3 to determine method (flag 2 was supposed to be strength but was never used)
- Merge two functions that did almost exactly the same thing (namely altering a terrain space and potentially updating conveyor/lights info)
- Merge switch_level into handle_lever since it was the only place it was called
- Remove global store_special_loc; the location is stored in the stuff_done array now
- Change when use/step on terrains will now update lighting if they changed to a terrain with a different light level
- Terrains that call a special no longer support mixed global/local modes - they either always call a local special or always call a global special
- Use previously unused swap_ter function (which did the exact same thing as the swap terrain special node)
Dialog Engine:
- Don't "erase" invisible icons or buttons; it's not necessary, since the entire window is filled with background before the draw() method is called, and it causes problems in case of overlapping elements.
