Fixed RequireJS build path.
Bootstrap Integration: Navbar

Created custom walker for generating the navbar also created
a custom fallback function for when there is no navbar.
Made some better styles for navbar.

Mainly two changes where made:
1. Dropdown menus will be revealed useing css when you hover over
them in desktop  computers.

Note that tablets and phones still have to click to see a dropdown.

2. Menu items will now float right on desktops and tablets.
Phones stay the same.
