Well... I didn't want to commit this before creating single-button
forms for enabling/disabling modules. However part of this accidentally
made it through, so let's finish it.
Still some work to do, but it already looks far better like this.
refs #4095
The controller is still pointing to the former view script, it will
soon be replaced by this ones. As soon as I created two forms handling
enable/disable requests this will be completed.
