Warning to users of some vendors LCD keypad shields

A few more photos.

NOTE: 2014-02-16
I have attached a zip image which contains a text file that details some s/w only workarounds.
(I used a zip image because the forum messes with line endings on text files and
I wanted the file to have DOS line endings to support the users still using Windows)

**NOTE:**2014-04-16
updated 2nd photo to show back side of header.
The diode attaches to a trace that goes behind the header and wraps
around to Arduino pin D10. It does not connect to Arduino pin D8.
