Revamping navigation bars

Implemented Bootstrap, changed the navigation bar when you are logged in.
Implementing Main nav bar

This code isn't quite ready to deploy, but I am trying to make it work in chunks.

This added Bootstrap. Formatted the main nav-bar when logged in, and replaced the search bar with something else.

Search bar logic needs implemented.
Added new icons to navbar

Added the new white icons with the blue hover states to the navbar
Navbar/header edits

I have reformatted the nav bar, almost 100% complete.

Changed the callout on the main page, those Blue arrows were not working. Also, the "SIGN UP" buttons do the EXACT same thing as the "LOG IN" buttons,
So instead of having a clunky drop down, you can do it right from the main nav bar.

Waiting on Revamped icons for the Login Buttons.
Pulled in master to make sure automerge will work for the pull request.
