Completer and losing its focus

[GoogleCodeExporter]

Steps:
- try to complete something. A scroll list will appear
- click outside of the scroll list

Expected behavior: 
- the scroll list disappear
- the focus or the text cursor moves to the place where the click happened

What really happens is the only first part. The scroll box disappears however 
the cursor or focus is not transferred.

I think it is related to how QCompleter is implemented. It consumes the event 
so it is not delivered to the other widgets.
