Title: Adds scheduling check for teachers teaching both blocks of lunch.

A debugging note: I had trouble loading the scheduling checks page with the debug toolbar on. I did my debugging either with the debug toolbar turned off from django_settings, or commenting out all of the other scheduling checks (which, the way the page is written, will work just fine). The latter approach also makes the page load in a reasonable amount of time, and might be useful for debugging query performance.
