This allows ALL settings in the gfx configuration dialog to be adjusted _per game_ in a more user-friendly way than before.
Obsoletes the gfx related options in the ISO properties, but I kept those since the configuration profiles use different ini file keys (i.e. convert the game inis to the new naming, please!).

Also verify the validity of gfx configuration directly after loading rather than in the GUI code (which was kinda stupid anyway).
