Bugfixes for tab view click events:

* When adding/removing tabs, process a fake mouse moved event to synchronize
   with the new tab layout.
 * Count the mouse clicks for the "double click into empty area opens new tab"
   feature in such a way that clicks into tabs never count (closing a tab was
   the first click before, the second would immediately open a new tab and
   similar issues).
