mu-plugin support added

I added code to the plugin to show dependencies on MU plugins. This might sound counter-intuitive, as MU plugins cannot be deactivated–and MU plugins are handled pretty differently than regular plugins. But, I added this to help administer their dependent plugins. In our case there are dozens of plugins dependent on one of several MU plugins. Now we can see at a glance which plugins depend on which MU plugins. Since we found this helpful I thought other might as well.

I don’t see this plugin’s code on Github. If you post a repository there I would be happy to fork and submit a pull request. Otherwise, let me know what your thoughts are about this feature.
