Moved per-game graphics configuration to the game-list right click menu. It will be too difficult to make the "profiles" drop-down thing work with 3-state vs 2-state checkboxes. The per-game settings now have "undetermined" states, except for the radio buttons(I'll fix that later). It's super hacky right now. Video config (probably all config stuff) could be redone.
