that try to utilize all the CPU in the computer. This behavior is harmlfull
when there are several testReciptRecongnition is running in a testnode which
has 40 CPUs.

To get the listbox cell value : code was getting last proxy target
instead of browsing the full proxy target stack.

Activate copy/paste/delete buttons on form list and form view.

When selection listbox lines, only use what is visible / checked.
This is required because of list methods which do not support catalog queries.

This changes the behaviour of mass workflow transition action and delete action,
but at least, it is consistent everywhere now, and so, easier to explain (what you see is what you change).

The listboxes in mass delete / state change dialogs are only used to confirm the lines selection.
