1. undid my wrong fix to wxWindowBase::Centre

2. corrected fatal bug in wxCheckLstBox (double deletion of items)
3. wxTextCtrl::SetValue() only does it if the new text is different from
   the old one
4. wxBitmap(const wxIcon&) ctor added
5. compilation fixes for VC++ and generic Win32 implementation of
   wxGetCurrentTime() in timercmn.cpp
