Version two of the Serial LCD circuit.

This version of the board looks a little better.  Wired the ground and +5v on the back (and one data line) to reduce the number of line crossings.  There are still two but far better than the first layout.  It follows the same schematic from the original post.  I also added a 470 Ohm variable resistor between the backlight (Pin 15 of the 16 pin header) and the +5v.  (My Dremel skills need reevaluation.)
