Had to change the link to the current language version of the page by a
button, to prevent following a link when trying to expand the submenu.
At first i did this with an `onclick="return false"` bullshit, but the
link was the wrong thing to do here, and it was there only to satisfy
Google et al. They will have to with the links in head.
Also made the link and buttons larger to make it easier to hit them with
finger.
