Reading the template of the invites page it was the intention of the
author to display the aliases instead of user refs if they are
available. The code loading the invites wasn't properly loading the
aliases of the useres who created them though always leading to this
data not being populated. This fix populates the aliases when listing
invites.
Additionally turned the invite author field into a link. This requires
some extra styling.
Fixes#245.
