GUI mode - manual construction

Just as in the prompt/script UI mode, the molecules, residues and spins can be manually added. First add a molecule by right clicking on the ``Spin system information'' element and selecting the relevant entry in the popup menu. Then right click on the newly created molecule container to add residues, and right click on residue containers to add spins.
