From Fabian Lavignotte, "Here is some various small fixes i have done while playing with

osgAnimation.
 - Animation : removed the _name attribute that is never used.
 - BasicAnimationManager : fix a crash on Windows with the example
osganimationviewer. The _lastUpdate attribute was not initialized when
using copy constructor.
 - CMakeLists.txt : add RigGeometry to the headers list"
