More robustness for the spin viewer GUI window prune_*() methods.

When no spin data exists, the self.tree.GetItemPyData(key) call can return None. This is now being
checked for and such None values are being skipped in the prune_mol(), prune_res() and prune_spin()
methods.

The problem was found in the Mf.test_bug_20479_gui_final_pipe system test when running the command:
for i in {1..10}; do ./relax --gui-tests --time -d &>> gui_tests.log; done

Racing fixes for the General.test_bug_23187_residue_delete_gui GUI test.

Some GUI interpreter flush() calls have been added to avoid racing in the GUI. The GUI tests are so
quick that the asynchronous user function call will be processed at the same time as the spin viewer
window is being created, causing fatal segmentation faults in the test suite.

Updated the copyright notice for 2015 in the GUI splash screen graphic.

The copyright notice in the GUI now uses the info box object.

This is for the status bar at the bottom of the GUI window. This removes one place where copyright
notices needs to be updated each year. This status text will then be updated whenever the info.py
file has been updated.

Updated the main relax copyright notices for 2015.

Updated my copyright notice on all files changed in 2015.
