Added QAccessibleGroupBox

Added a new accessible interface for QGroupBox, as QAccessibleDisplay
is not good enough when the QGroupBox is checkable.
AccessibleFactory was modified to return a QAccessibleGroupBox when
the accessible interface of a QGroupBox is requested.

Created tst_QAccessibility::groupBoxTest

Port to Qt5 of the patch by José Millán Soto <fid@gpul.org>
