Quite some information is missing from
the list of installed plugins; and the
list of installable plugins has some
more information, but not everything
that is present on Spartacus, i.e.
the last modification date.
So let's add a link to the plugin entry
on Spartacus (in the chosen language
version).
Fixes#471.
