Update layout

Here is an update of the layout with hookups for the FTDI and the "Arduino (Nano) as IPS":

The resonator (i.e. crystal and loading capacitor package) has been replaced with a conventional (i.e. larger) crystal. The schematic shows an 8 MHz crystal but a 16 MHz is still okay proving the power supply is 5v.

Note that the 10R resistor now shares a hole with a wire link (red) so that ARef equals AVcc (a previous oversight).
