Add next round of .rst Documentation files

Create .rst documents that match the pages that user kthlnkeating added
to the Wiki pages about setting up the testing environment.

Pages to match:
http://www.osehra.org/content/obtaining-vista-foia-code and
http://www.osehra.org/content/automated-vista-configuration-and-automated-functional-testing

Add a page that explains the format and contents of a typical KIDS patch
file:
http://www.osehra.org/wiki/kids-format

Edit ImportCache and ImportGTM to remove the references to cloning the
Vista M repository.  These commands would duplicate the information in the
ObtainingVistAMCode.rst file.
