Using devise for auth
Added an admin dashboard
Updated admin panel
Rebecca: Added devise auth for admins. The home controller shows a login form for admins, and the page changes to allow creation of a category, delete a job posting, etc.

Make sure to run 'rake db:migrate' and 'rake db:seed'. Your email/password combo can be seen in db/seeds.rb :)
