Add a URL and external directory to the menu definition

Now, a menu entry can target not only local content, but also a URL to
external resources or a remote directory managed elsewhere (i.e. a
directory on the installation target).

In other words, it is now possible to create a link in the menu to an
external website or other server-managed content, such as an HTML
interface to git repositories.
