Version info debugging works now even without native libs.

 - Platform is now useable without gluegen-rt libs in library path.
 - JogampVersion: fixed equals, added Impl url to manifest.
 - VersionUtil: getManifest should be now more relieable and passed all manual tests, e.g java jar lib.jar without specified classpath.
