Title: improve CSS for site navigation bar (bug 1082161, bug 1083613, bug 1083614)

# tasks completed
* remove unused rules, optimise selectors, and make things more OOCSS-y
* improve navigation hover states ([bug 1082161](https://bugzilla.mozilla.org/show_bug.cgi?id=1082161))
* use CSS instead of JS to toggle category drop-down on desktop ([bug 1083613](https://bugzilla.mozilla.org/show_bug.cgi?id=1083613])
* add borders to desktop navigation items ([bug 1083614](https://bugzilla.mozilla.org/show_bug.cgi?id=1083614))
* fixed CSS to actually hide the link outlines on focus
