Added a banner that students can use to dismiss the "you have failed reverification" message.  Also, removed unused code, wired up the sidebar for design

Added verification sidebar, banner for major courseware sections, quality & test improvements

Improved tests, fixed javascript for photocapture, removed extraneous photocapture code, added time & course numbers to templates for design

Quick-and-dirty end-to-end flow, functional for at least the case of one course in need of re-verification.

Ready for design to start taking a look; still needs tests and code cleanup
