[BUGFIX] Module menu clicks with slow connections opens standalone module

If loading the backend using a slow internet connection an early click on
any item in the module menu on the left side causes the link to be opened
directly. The reason is, that JavaScript and thus click handlers are not
completely loaded yet. Thus, the regular DOM behavior of anchor tags is
executed.

To circumvent this behavior, href-arguments have to be disabled and the
module URL moved to a dedicated new data-attribute. As a result all items
that trigger a module change have to be adjusted as well.
