bug 1876 - allow command separated URL's in 'convenience mode'
bug 1876 - allow command separated URL's in 'convenience mode'

To incrase moxi ease of use, when moxi sees comma-separated
http://host/some/json URL's as the last parameter on the
command-line...

  ./moxi http://host:8080/foo/bar,http://host2:8080/foo/bar

Or...

  ./moxi http://host:8080/foo/bar

It will convert that underneath-the-hood to '|' delimited URL's,
like and proper -z url=LIST_OF_URLs...

  ./moxi -z url=http://host:8080/foo/bar|http://host2:8080/foo/bar
