Mobile site-nav menu not doing anything

[g3wanghc]

When the class showmenu is added to the body, any click event on the body will trigger the function closeMenu. The function disables the default action on the DOM, making redirections impossible.

As suggested by @arkon: "It might be better to just check if e.target was inside the .trigger element instead of adding the class."
