Got DES encryption of password working and colors corrected.

- DES encryption for VNC bit mirrors every bytes of the password. This
  commit has a hard-coded mirrored password. Need to ask user and bit
  mirror it.

- With image data across the wire it's Blue,Green,Red, so twiddle
  things around a bit.
