Resolves #42: Added a couple of timestamp fields.

This is (yet another) backwards-incompatible DB change. Just taking
advantage of the opportunity, really, since the other incompatible
changes haven't been pushed live yet.
Resolves #40: Added a template header that links to the home page.
Resolves #43: Reworked the footer's (and general template's) styling.

Set out to make the footer's "stickiness" work correctly, but decided I
didn't like it being sticky at all.

In the process, decided that the site looked better using non-fluid
containers, so switched to those.
Resolves #41: Timestamps on the home page are now pretty-printed.
Resolves #44: Force failsafe to use a "normal" classpath during ITs.
Removed an unused import.
Updated the work log.
