OGR STYLEITEM AUTO: Symbol Point doesn't support rotation and outline color

[aboudreault]

In mapogr, the symbol styles supported are actually: color, size and symbol id (name in the mapfile). It should be possible to support these symbol styles also: (in MapInfo? terminology)

• Rotation: The angle for the symbol rotation. (OGR style: OGRSTSymbolAngle )
  Already supported by mitab and gdal. This will simply be added in mapogr.cpp.
  

• Halo: The symbol use a white border. (OGR style: OGRSTSymbolOColor )
• Border: The symbol use a black border. (OGR style: OGRSTSymbolOColor )
  These styles has been added to mitab and gdal, see the related bugs:  http://bugzilla.maptools.org/show_bug.cgi?id=1925
   http://trac.osgeo.org/gdal/ticket/2509
  

These symbol styles will be added like others similar styles (OGRSTSymbolColor, OGRSTSymbolSize)
