Added function to get total adjusted payment for an Order Set

Changed RVU.total_cost() to use multiplier (needs to be passed an instance of 'MyUser' now)
Bootstrapped dropdown button in search results
added new template tag for passing user to method
change navbar when user is logged-in
Don't know why I put 'legend' tags everywhere instead of h1's, but now they're h1's again
