Fixed some minor bugs

1) The custom directory paths in the config could contain unwanted junk at the end if the loaded config file was saved from real FT2 2) If you were skilled enough to beat the very last Nibbles level, your potential entry in the highscore table would show garbled stage graphics 3) Show a warning if either of the Buttons/Desktop palette colors are so dark that you might have issues seeing the walls in Nibbles
