_s: rework nav JS file a bit

* Remove top-level browser width variable, only needed in one internal function
 * Add timeout so that the resize action doesn't constantly trigger, instead give it a short delay to anticipate the user finishing the window size change
 * Better comments
 * Incorporate mattwiebe fix for calling jQuery objects incorrectly, see http://core.trac.wordpress.org/ticket/20131
