Changes in SuperWaba 1.12

. changes in class waba.ui.Window:
  . added support for more borders:
    NO_BORDER,RECT_BORDER,ROUND_BORDER,TAB_BORDER,TAB_ONLY_BORDER
  . the Window's constructor now accepts a given border number (instead of the
    old 'boolean border' option). Changed all Window controls to match this.
  . method setBorder renamed to setBorderStyle
