Fixed issues 3, 4, 6, 7, 8 in email

3. The pandoc template needs to be updated for the nav bar (Feedback
link).
4. While you're at it, please update the Submit link to:
https://markus.cdf.toronto.edu/csc148-2014-09/. It doesn't work yet,
but that's what it will be.
6. Please remove your tests from the Home page. They don't belong there.
7. Remove the text at the bottom of the "More" page.
Deyu’s note: other pages under More are created and so are their
corresponding links in every page.
8. The DCS logo should appear at the bottom of every page, and nowhere
else. (E.g., not in More sidebar).
