Extension:Multi-select Namespace Search

Have you ever been frustrated at namespace search checkboxes? I know I have. A multi-select menu makes more sense here, I believe.

This "extension" is more of 2 rewrites of files in the includes directory: SpecialSearch.php and SpecialPreferences.php which contain namespace checkboxes. This hack was tested on MediaWiki 1.9.3 so it may not work for older/newer versions. Please mention here if it does.

Unfortunately, not being that much of a PHP coder, I haven't been able to figure out how to get the select form to output the option name so it equals ns0=1&ns1=1, etc. The select form will output its name but the option fields won't, for some reason. If you can figure it out, please edit this code accordingly. Thanks.

SpecialSearch.php
In this file, the only function changed is:

SpecialPreferences.php

Copy SpecialSearch.php</tt> and SpecialPreferences.php</tt> into the includes</tt> directory. I'd advise making backups of the existing files.
