Renamed all files to intended destination packages for JSR-231. The

only package specified by the JSR is "javax.media.opengl". The utility
package com.sun.opengl.utils is Sun-specific and optional. The Cg
binding has been moved into com.sun.opengl.cg. Moved Animator and
FPSAnimator to com.sun.opengl.utils. Updated and tested demos with new
source code locations.
