UI/Qt: Manually paint the tab-bar background where the "add" button was

Browse source 
The TabBar itself does not stretch the entire width of the TabWidget,
because it leaves space for the width of the new-tab button. So, we
manually tell Qt to paint the TabBar's background into the gap.

Fixes #768.
