wxWidgets/include/wx/textctrl.h
Vadim Zeitlin b7421ab625 Move wxMSW wxTextCtrl::GetDefaultAttributes() to wxTextCtrlBase. 
This commit doesn't introduce any changes in the control behaviour, it simply
moves the existing method to the base class because it is not MSW-specific.

Also implement wxTextCtrlBase::GetClassDefaultAttributes() because if a class
implements GetDefaultAttributes() it should implement it as well.
