Added save state for testing implementation of error analysis.

Task #7882 (https://gna.org/task/?7882): Implement Monte-Carlo simulation, where errors are generated with width of standard deviation or residuals.

Improvements for the rdc.corr_plot user function - the plot range is now determined by the data.

Improvements for the pcs.corr_plot user function - the plot range is now determined by the data.

Fix for the rdc.corr_plot user function.

The Y-axis is now set to the measured RDC, as the RDC errors are plotted as dY errors. This matches
the behaviour of the pcs.corr_plot user function.

Improvements for the plots created by the pcs.corr_plot user function.

The axes now have labels, and have the range and number of ticks set to reasonable values.

Small whitespace formatting fix for the titles printed by the align_tensor.display user function.

Created a development document for catching segfaults and other errors in the GUI tests.

This is needed as not all wxPython errors can be caught in the Python unittest framework.

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

The data returned from the self.tree.GetItemPyData(key) call can in rare racing cases not contain
the 'id' key. This is now being checked for and are being skipped in the update_mol(), update_res()
and update_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

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

More robustness for the spin viewer GUI window update_*() 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 update_mol(), update_res() and
update_spin() methods.
