TODO

TODO:
    - Record more things (times that techs are complete, etc.)
      for both "scores" and general statistics:
        # saves.
        # Bases constructed (per type)
        # Bases discovered (per type per news/science...)
        # Bases destroyed (per type)
        # Money earned (huge)
        # Time to completion
        # of upgrades for all bases
        # per-tech time to completion (from day 0 to start, then time to completion)
    - Add more items.
    - Consistent use of stderr and print, preferably using available Logger
    - Create a hook for dialogs to auto-detect hotkey conflicts
    - Detect user's desktop resolution and set game's default resolution
      accordingly. For windowed mode (current default), leave room for borders
      and panels. -50 for width and -70 for height seems a sensible number.
    - Use the difficulties list and names in creative ways, such as:
      - display current difficulty in options screen instead of map, or,
        even better, in map's menu dialog (Load/Save/Options/Quit)
      - disable difficulties not beaten by player, keeping track in prefs.dat

    - Current Theme system works, but it sucks in many ways:
      - weak support for changes other than background night/day map image
      - code for changing theme values (images, fonts, etc) through game screens
        should be compatible with the upcoming on-the-fly i18n of texts and
        labels when language changes. See testing/options branch in git repository.
        Its propagating mechanism also sucks, so find a good, consistent and
        preferably unified way for both to propagate changes to all screens.

    - Last but not least: fix all the issues found at
