Created name method for Legislator

Created a method that joins all the names for legislator and then had
that delegated in bills so that it can easily access the full name of
that legislator.
Navbar updated to show current area

Active areas in Navbar works as well as removing the section for
Results.
Routing and structure made to fit RAILS convention

I was doing my own thang and was bit by it. Now following the rails
convention of having show display a single instance of something. Also
having index list things. Removed the profile page for legislator and
use show now like the cool kids.
