More new features for the CMS

More new features have been added to the CMS.

Log in from anywhere
Beginnings of user and group rights system
Admin menu accessible from anywhere with correct user or group rights
Templated menu and admin menu

Next up is a re-working of the admin interface to clearly label some of the functions that don't list what they actually do if they change them, template the admin interface, and add in admin options for the new rights features.

After that I believe I will release the new CMS code on this site on the off chance that you happen along here and want to play with it.
