Fix to _navigation-toggle.scss #navigation-toggle, missing closing bracket

In the current _navigation-toggle.scss you have this:

#navigation-toggle {
list-style-type : none;
@include zero;

@include media-query-bp($bp3) {
margin : 0 0 0 -0.25em;
border-width : 0;

li {
display : inline-block;
margin : 0 $gutterwidth / 2 0 0; }
}
}

ul {
list-style-type : none;
@include zero;

@include media-query-bp($bp3) {
margin : 0 auto; }
}

There should be a closing bracket } after the first media query (before the li selector). There should then be a media query call within the li selector. A perfect example of this can be seen in the _navigation-responsive-nav.scss.
