This reverts commit 14b46e2183.
This functionality will need to be rewritten to work with the new
OpenIDPlugin.
Conflicts:
index.php
lib/logingroupnav.php
If $config['site']['openidonly'] is set to true:
* the Login/Register pages will be removed from the navigation;
* directly accesses to the Login/Register pages will redirect to the
OpenID login page;
* most links to the Login/Register pages will link to the OpenID login
page instead.
The user will still need to set a password to access the API and RSS
feeds.
