Subject: [PATCH] Added an `interactive' flag to new_game_desc(), which toggles
 Mines between on the one hand generating indeterminate game descriptions
 awaiting the initial click, and on the other hand generating concrete ones
 which have had their initial click. This makes `mines --generate' do
 something useful.
