Converts a 32x32 sized, 24 bit (32K colors) bmp file into a saved Fill It Up level. Right now only red, green, and blue colors can be used. The greatest value color determines the color tile to be used. So if a pixel has a rgb value of  200,100,34 then the tile will be red. If there are more than one greatest value, then the tile will be a blank tile. The starting position will always be saved in the top left corner.
