Create mechanism for plugin URL checking

[JTFouquier]

Despite the fact that we have a system for users to report broken plugins, it's apparent that most people don't. (e.g., Human Protein Atlas is one of our most used plugins, and that one didn't get reported...) So I think we need to build some sort of system so that we can review plugins in a fully- or semi-automatic method. It doesn't have to be perfect, but we need to do something...
