1) SMESH_Mesh: add methods to get complete information of nodes, elements, submeshes

2) SMESH_MeshEditor: methods adding elements return their IDs;
3) SMESH_MeshEditor: add ChangeElemNodes()
4) SMESH_MeshEditor: add GetLastCreatedNodes() and GetLastCreatedElems() to get results of complex operation
