[libgdx] Added Mesh#newLinkedMesh(), creates a linked mesh linked to either the original mesh, or the parent of the original mesh. Changed behaviour of Skin#copy: it always creates linked meshes. This allows changing e.g the region or rendererObject of the mesh, but will still link to the original mesh for vertices and similar data.
