Subject: [PATCH] Add array support to wfArrayToCGI(): when receiving
 parameters in the form of &foo[]=bar&foo[]=baz, PHP automatically sets
 $_GET['foo'] = array(bar, baz); When feeding the original query back to
 wfArrayToCGI(), it used to choke on that. Now wfArrayToCGI() actually
 converts array('bar', 'baz'); back to the &foo[]=bar&foo[]=baz form.
