Filter objects in a View according to the user profile variable

One of the Blippa customers wanted individual Views for their partners, each view only showing objects installed by each partner.

So, we used some magic, and now the View can contain a selection.

This uses the user profile variable of the logged-in user to display objects belonging to the same company as the user.
