1. big wxScrollBar optimization: Refresh() doesn't refresh them any more

2. many fixes to refresh scrollbars when needed (as this is not done all
   the time now)
3. wxStdButtonInputHandler bug with uninit m_hasMouse fixing bug with
   moving mouse with pressed left button into button
4. wxRadioBox::SetSelection() and wxRadioButton::SetValue() clear the
   values of the other buttons in the same radio group
5. wxTextCtrl::RefreshPixelRange() calculates the end of line correctly
6. tons of wxListBox fixes
7. removed confusing "Create" button from the lbox sample, listbox is now
   recreated on the fly
