With the latest version of Bootstrap, 3.0.3, they changed how padding works with .navbar-right:last-child.
Fixes BlackrockDigital/startbootstrap#27 by adjusting padding.
By adding 15px of left and right `padding` on `.navbar-collapse` the conditions in which the page was originally made are replicated.
Though this may cause other issues, I have not been able to find any.
