[osg-submissions] add multiple-animation-path output capability to ViewerEventHandlers.cpp

[Robert Osfield]

Thanks Bob, changes now merged and submitted to SVN.  I tweaked the
filename creation code so that the the number increment is now placed
after the file name, so you'll get saved_animation_01.path etc, I also
reduced the 0 padding from 4 characters to 2 as I can't image needing
thousands of animation paths...

Robert.
