    Contacts.Window: "Done" button actively grabs focus
    
    Some input fields, especially SpinButtons, do not update their internal buffer if they do not drop the 
focus. If you enter a number into a SpinButton input field without leaving it, press the "Done" button and 
the button does not gain the focus then, the newly entered value of the SpinButton gets lost. Hence the 
"Done" button gains the focus on click now.
    
    Fixes #82
