Don't quit while dive is edited

If the user edits a dive and then quits we try to ask them to finish
editing, first. If the user did this by either clicking the little 'x'
in the window decoration or by hitting Alt-F4 (or similar), we didn't
have that question (only the 'save changes' question in case the dive list
had already been modified.

Fixes #374
