pre-user-testing front end changes

@christensenep can you merge this into yours to make sure we're on the same page and the let me know what latest branch I should work off of... thanks :-)

Based on convo with @iamjessklein && @xmatthewx 

INCLUDES: 
pre-testing front-end priorities:
Add color to edit and view, save changes buttons (they look inactive)
and some kind of hover state
Formatting on the "landing page" seems off (should at a minimum be 2 columns)
Jess's screen: http://awesomescreenshot.com/01828ped22

let's temporarily use logged in header
responsive for *other* screens
Applications listed on the navigation 2x
