Updated master config file to 2014.7

Fixed explanations, and improved logic code to client_acl
Initial add of dummy saltify settings

This commit also provides a more concrete example of a 'host' to
be saltified.  Users can do

    salt-cloud -p make_salty someinstance

or

    salt-cloud -m /etc/salt/cloud.maps.d/foo.conf

Either which way the online docs should really be updated with more
concrete examples.
