Update to JOGL 2.1.5-01

The latest changeset brings jzy3d to version 2.1.5-01 of JOGL and gluegen and fixes compilation errors due to API changes. This solves most issues with NEWT lockups especially on Linux that occured with the previous versions. The changeset also provides a fix for a NEWT/ICanvas - related problem in View when the current GL context was to be retrieved from a GLAutoDrawable (https://github.com/jzy3d/jzy3d-api/issues/10). Another issue due to the API changes in JOGL 2.1 is also fixed (https://github.com/jzy3d/jzy3d-api/issues/33).
