Subject: [PATCH] Added support for reading a .osg style data from a file
 string when trailed by a .osgs extension i.e.

  osgviewer "osgTerrain::Terrain { ElevationLayer { CartesianLocator 0 0 1000000 1000000 Image ps_height_512.tif } ColorLayer { CartesianLocator 0 0 1000000 1000000 Image ps_texture_1k.tif } }".osgs
