Navigation

My previous error was due to the nav.js file not being referenced properly in the layout.erb file.  

Here is a functional navigation menu that jumps down to the following locations on the website: 
Prizes  Judges  Sponsors  Sign-Up

I believe it looks fine on mobile but on a standard webpage the menu stays justified left.  

There is still a bug in the way the menu slides right about 1px every time someone scrolls starting from the top.  It's unnoticeable unless someone scrolls about 4 times at which point the "Join" link will move down one line.  
Should this be `Sponsor Prizes`?
