Analysis scheduler

The primary goal is to add a "scheduling service" to the analysis web app.
This PR also resolves bug 961200 and improves the UI for the debug/worker launcher.
You can see a live version of the app running here:

Beware that it works, and will really try to schedule and run any jobs you create (though you can delete a job after you've created it).

This is a fairly large blob of code, so please ping me if you want me to walk through it with you.
