Fix crash caused when exiting.

The lost focus event was triggered to the central widget.
Since this widget does not map to a qt widget, there is
no wxWindow derived destructor for it, so the handler
must be set to NULL from the frame.

Simplificate QWidget* assignment (new PostCreation method)

Also reducing the redundant m_qtWindow code, this could help to unify application of background style and default colors (for painting, that was not being enforced and could cause issues). Window style code is commented in the original, maybe it belongs to wxFrame.
PostCreation method name was taken from wxGTK, that has similar features.

Implement missing wxQT helpers for QLabel

This now is needed to correctly paint the background, allows the static text / bitmap to handle events and signals, and maybe a better destruction process.
