Cannot set renderer on Ghosts

[Jan-Wijbrand Kolman]

While pursuing a solution for issue1173, I found that, although XML producers
are registered for Ghost objects, they cannot actually be used becasue the SMI
wil not show the 'set renderer' UI in the tab_metadata for Ghost.

This is because the form elements for setting this property is implemented in
the metadata macro, more specifically in the macro for the edit table which is
not shown for Ghosts.

We should move the form elements for setting the renderer to a different location.

Assigned to me - not that I have clear idea yet what to do about it.

Should this be fixed for 1.1.1 too? It would sort of make sense to do so I
guess, since we try to fix 1173 for 1.1.1. as well.

This issue highlights a problem in the user interface. To fix it requires
changes that shouldn't happen in the 1.1 branch. Moving to midterm.

In the Silva trunk, I do see the "set renderer" form in the settings sub-tab, so I think this issue has been cleared up...
