Fix UI confusion of starting Sleep Tracking
Used UI app, created/fixed templates, updated settings/urls

The new system has a dashboard for users that are logged in and has a
home page for users that are logged out or people that are planning on
signing up. This created the home/dashboard pages dynamic so they can
check to see if they have already started tracking there sleep and
forward them to the dashboard. On the dashboard page it only displays
the sleep tracking start link if a user has not started sleep tracking
and is hidden and visually replaced with a link that goes the sleep
tracking day selection.
