Return users to top of list when they go to a new page
Made the log in/sign up modal instead of individual pages.  The original
intent was to use this technique to solve the "how do we store
information and return users to their previous position" problem.  And
it works in some regards, but introduces other issues.  Specifically in
regards to refreshing page content.  Regardless, I think we might keep
the modal concept.
