Badge hangs in demo mode

[FirewallDragon]

There's something wonky with the JPEG processing. In demo mode, which continuously cycles through all the available modes, it will eventually hang while updating the LCD with a new image. I'm not sure what the cause is yet, but I know that the JPEG library was a little touchy. For example, sometimes I'd optimize a JPEG and it wouldn't even load. I'm not in a big hurry to fix this since DEF CON is over now, but if you have any thoughts or ideas, feel free to comment.
