disable painting updates when adding/removing a workArea. This fixes these spurious messages with Qt4.1:

When opening another document, the following is printed to the console:

QWidget::repaint: recursive repaint detected.
QPixmap::operator=: Cannot assign to pixmap during painting
Painter must be active to set rendering hints
[repeated many times here]
Painter must be active to set rendering hints
QPainter:🔚 Painter is not active, aborted
QPixmap::operator=: Cannot assign to pixmap during painting
QPixmap::operator=: Cannot assign to pixmap during painting
currentTabChanged 1File/c/work/file2.lyx

and, when closing LyX:

QPixmap::operator=: Cannot assign to pixmap during painting
QPaintDevice: Cannot destroy paint device that is being painted.  Be sure to QPainter::end() painters!

I suspect that solving these issues might also solve the missing close
tab button problem.
