1. wxStaticBox doesn't draw over the underlying controls any more

2. a couple of new helper functions in msw/private.h: wxColourToRGB and
   wxRGBToColour are handy to avoid writing horribly long and ugly RGB <-> wxColour
   conversions explicitly
3. modified wxDirDialog to be more comprehensible (to me), hopefully it also
   works better
