[2.0-wip] Navbar .container width

Created by: simonyeldon

The docs refer to having a <div class="container> within the navbar however, there is no overriding .navbar .container style to reset the container width to its parent's.

When you use the responsive layout with the collapse plugin, this makes the collapse button overhang the right side of the navbar.

Solution would be

.navbar-inner .container {
    width: auto;
}
