readme had typo

(also posted in bugfixes)

Ive just been made aware that there was an error in my (readme.txt) pinouts.
I originally had the Serial-In of the Shitf registers going to Arduino P12 (MISO)..
It should have read P11 (MOSI) (see *) below..

___|-----|____ (key on top)
| P4 P6 P8 P11* GND |
| P5 P7 P9 P13 GND |
--------------------

Sincere apologies to anyone that had been misled by this error.

ArdvtLedBoard.0.2.0715 contains the updated readme.txt
