Updated User Profile Page

#204
The user profile page has been re-hauled to include the weight tracking graph, experience progress, and the general appearance.  I also changed a few small things outside of the profile page (eg. took out the update panel in master page).  

There's currently a bug for the graph that when you click the update button the graph disappears.  This is because the javascript for making the graph doesn't get re-executed, and I wasn't sure of how to re-execute it (OnClientClick="AmCharts.ready()" didn't work).
