[Mono-winforms-list] Clipboard.SetDataObject() doing nothing

[Ivan N. Zlatev]

Hey,

There is already a bug for this:
https://bugzilla.novell.com/show_bug.cgi?id=357642

Basically we don't support IDataObject and custom data (clipboard)
formats and just hand-check for text and handle that in a magical way.
The best way (imho) to fix this is to have a IDataObject centric
clipboard implementation. I have some notes if someone is interested.
