these are odd - maybe need to re-install since somehow an empty path is getting passed in.

note this turns out to be more than a cosmetic fix - if the address is set to 'rpc.acquia.com', parse_url() returns that value for 'path' rather than 'host'.

oops - and a new notice from the theme function override.

Hmm, turns out admin_menu doesn't even use the 'attributes' - so we should be adding the class to 'extra class'.

Also, we should delete the admin menu link if the module is disabled (oesn't happen automatically since it's an external link).
