Bootstrapped styling and application layout.

This completes chapter 5.1, 5.2 of the rails tutorial.  5.2 referred to
SASS rather than LESS, so I essentially ignored that piece.
Static routes converted to named routes.

The routes for contact, help, home and about have been converted into
something much more relevant - /home, /help, etc., rather than directly
to static_pages/...html.

This important concept is one that I'll have to make sure I spend plenty
of time trying to remember.
Footer display complete.

This doesn't display the way I want it to, but I'll just deal with it
for now, as I want to get into the meat of the tutorial.
Simplified test cases for static pages.

This marks the end of chapter 5.3.4.
Signup page with tests.

This completes section 5.4 of the Ruby on Rails tutorial, by adding a
new controller, route, and specifications for that route.
