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.
