From Ulrich Hertlein, "attached are some minor tweaks:

- fixed typos in osgViewer/ViewerBase
- const-ness in include/osg/View findSlaveIndexForCamera
- supported options for STL reader, fixed return values to reflect proper errors
- supported options for DirectX reader, fixed return values
- normals pseudo-loader: scaling normals to a const (but variable) fraction of the bounding sphere radius
