The entry ac.deactivateLogin in the Erfurt default.ini needs to give visual feedback if it is activated

[shinobu]

The entry ac.deactivateLogin in the Erfurt default.ini needs to be more visual in OntoWiki, as the LoginModule doesn't give any visual feedback, that the login is turned off.

=> The Login Box should either be removed if login is deactivated or should have a warning in it that says, that the login is deactivated
