TAdvPanel - CanMove & MinMaxCaption cannot work together

When CanMove = True, MinMaxCaption feature does not work. Internal hittest method will let CanMove work, but not MinMaxCaption when the former is True.

OnCaptionClick (and maybe OnCaptionDblClick too) neither fires when CanMove = True. Same HitTest problem.

These features are mutually exclusive. When CanMove = true, the caption is solely used to drag the panel to another position. It uses the Windows mechanism WM_NCHITTEST, HTCAPTION and this blocks click messages in Windows.
