Fixed crash if you used the swapdemo command incorrectly

Added letterboxing of the game based upon your resolution option so the game maintains the correct aspect ratio based upon your resolution choice. If you choose a "Normal" (4:3) and play on a widescreen (16:9 or 16:10) monitor then we will now place black bars at the edge of the screen to keep the right aspect ratio. The same is true for widescreen options on 4:3 monitors. Put "-stretchaspect" in the games launch options in Steam if you wish to disable this behavior
Added better detection for older GPU drivers and the functionality they support. This should fix the green bar or black screen rendering issues people have been seeing
