New GraXML Features

I have released a new minor version of GraXML. Besides bug-fixes, it has two new features: Right-click on objects in TreeView pops up menu with graphical operations applicable to associated geometrical object. User can choose one or several objects. Only leafs are supported. Some items perform directly the operation (like making object transparent or wireframe), Picking selects object for further actions (like changing of color via top-right panel). More actions will be added later, including interactions with associated programs (e.g.Atlantis). User can show a scene floor, which is placed below the scene. User using WebStart to call GraXML will get this new version automatically on next call. Both GraXML Web Start and Atlantis+GraXML Web Start are updated.
