Alert in missing plugin dependencies
It would be nice if FD would alert you if you have installed a plugin, but it's dependencies are not installed.
Let's say the only plugin I have installed is Samba. I should be alerted, that I need to install the Systems plugin. Having done that, Systems should warn med that I need the Argonaut plugin.
