Update site-wide stylesheet to use Sass
Downgrade to RSpec 2.13 and Guard 1.8
Don't use --drb for RSpec

Includes environment settings to enable notifications through Guard and
disables the Cucumber plan as we do not use Cucumber.
Remove rspec/autorun requirement

This is unnecessary when using Zeus.
Reorganize Gemfile

Moved gems that should only be used in development or test into the
proper groups.

Static page routes are now accessible from the root path, and the root
itself routes to the static home page.
Links to static pages use named routes
