Added test for osgPresentatation::Group::getSupportedProperties()
Added Action class NodeVisitor that supports osgPresentation nodes.
Added PrintPropertiesAction to osgPresentation
Added PrintProperties visitor
Moved the property test from the model to presentation to test out the property inheritance scheme
Added missing Model.cpp
From Alberto Luaces, "current versions of ffmpeg render «url_feof» macro as obsolete.  The fix
is very simple and it is contained in the attached file."
Fixed warnings
From Laurens Voerman, "like the "Bug in ProxyNode serializer" Farshid Lashkari found (svn submit 13754) the PagedLOD  serializer attempts to read begin and and brackets.
Fix is identical (don't read brackets when num_chidren is zero) and applies both to trunk and 3.2 branch."
From Colin McDonald, "Attached are some fixes to build osg using the Solaris Studio compiler.
I've also checked the modified files still build ok with other
compilers (Linux gcc, Windows Visual Studio).

osgDB/OutputStream.cpp and osgPlugins/lws/SceneLoader.cpp require
stdlib.h for atoi use.

In osg/Uniform.cpp the compiler complains that base_class is unknown
unless I add a class name qualifier.

Not a build fix, but I spotted a typo in osgUtil/SceneView."
