#011277: Dots in URL query parameter names are converted to underscores

This behaviour comes from the PHP function parse_str(). The Url component should preserve the dots.

Reproducing code:

$url = new ezcUrl( 'http://www.example.com/mydir?openid.nonce=123456' );
var_dump( $url->getQuery() );
echo $url->buildUrl();

This will output:

array(1) {
  ["openid_nonce"]=>
  string(6) "123456"
}
http://www.example.com/mydir?openid_nonce=123456

Operating System:
PHP Version: (please be specific, like '4.4.3' or '5.1.5')
Database and version:
Browser (and version):

See above for reproducing code.
