Heroku bug fix patch
Added buttons to links to imporve look/feel of application
When updating a student/judge/instructor the user would be logged out.  This is now fixed
Changed 'new user' to new student? to remove ambiguity.
Removed the judges name from the new jury form, as I assume the judge will know their own name
Juries now have in writing the final assessment when viewed by a student/judge.
Cleaned up top-nav bar ugliness

Changed nav bar to say "Musical Jury App"
When signed in as a user, now shows user name
