templates/vhost/_proxy.erb misconfigures ProxyPassReverse

See here:
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypassreverse

When enclosing ProxyPassReverse in a <Location> directive, you drop the
*first* argument, as it will be taken from the enclosing Location. The
second argument is the URL to which we are attempting to proxy.

Very simple change. Tested in my environment, works.
Merge branch 'master' of https://github.com/jrwilk01/puppetlabs-apache into proxy-pass-reverse
fix simple linting errors
disable lint check for "single quoted variables"

Previously we were checking (and failing every linting run) because
the values for Debian configurations uses a syntax that looks like
Puppet variables.  This is regrettable since it's a valuable check but
the fix will probably require changing how the conf variables are
handled which is out of the scope of this PR.
use a .puppet-lint.rc for usage outside of rake tasks
