* Added background graphics for bottom screen console * Used new font for bottom screen. A stripped down version of the misaki-gothic used by GodMode9i -> https://github.com/DS-Homebrew/GodMode9i/tree/master/resources/fonts * Renamed folders for bootloader and exception stub as I am not setup to deal with sub-modules at the moment.
