[NTG-context] please fix command reference links on contextgarden

it does *still* not work. the fuction is defined as such: function show_command(URL) { open_window().location.href='http://texshow.contextgarden.net/cmd/' + URL; } and thus redirects to some url under http://texshow.contextgarden.net/. but no matter what that url is, the subdomain always redirects to the url http://wiki.contextgarden.net/Category:Reference/en (no, not http://wiki.contextgarden.net/Category:Reference/en/TheCommandName!) please fix it, whoeveer runs texshow.contextgarden.net
