Commit 1c8ad24 removed all reads of `wind`, but did not remove its
assignment or declaration. This breaks the build with gcc due to
-Wunused-but-set-variable.
Fixes: 1c8ad24da3 ("Check for window_event_result::deleted for ui_get_filename polling loop")
Commit 917f079 removed all reads of `wind`, but did not remove its
assignment or declaration. This breaks the build with gcc due to
-Wunused-but-set-variable.
Fixes: 917f079f02 ("Check for window_event_result::deleted in ui_dialog_do_gadgets")
The functions med-mark-start and med-mark-end don't exist - that's fine, still read the rest of the menus, so it can actually properly 'hide' the help menu after it's clicked on.
If a game was playing, continue playing. If it was in the main menu, return to the main menu. (If all files are put in place the editor can load again.)
As the UI_DIALOG client is now responsible for freeing all gadgets (via unique_ptr's), this function now causes issues where it attempts to access freed gadgets (resulting in std::runtime_error("unknown gadget kind") exception when closing the AI Properties dialog on my Macbook, for example). Removing the offending function fixes the issue.
In particular, window_event_result::deleted so the event system doesn't have to rely on the somewhat problematic window_exists. If a gadget is manipulated, it still returns at least window_event_result::handled so all the other gadgets in all the other windows don't have to be checked (that weren't already checked).

Allow dcx::UI_DIALOG struct to be subclassed step 3. This step adds the destructor and makes sure the dialog is only deleted within the main dialog handler if the specific handler didn't return window_event_result::deleted.
Replace delete dcx::window kludge with a better solution: instead of requiring every handler to delete the window, add a window_event_result::deleted, which gets returned if the window was deleted by the handler, so window_close knows not to attempt to delete it again.
Allow dcx::UI_DIALOG struct to be subclassed step 1. This step renames and reconfigures untyped_ui_dialog_create in dialog.cpp to be the main constructor. Also adds a template constructor that allows an event handler that takes a subclass of UI_DIALOG.
Allow dcx::window struct to be subclassed step 3. This step adds the window destructor and both requires and implements the window to be deleted by the event handler/client in all cases.
