Added the document-close Oxygen icons.

All analyses are now deleted prior to loading the save file.

The synchronisation of analysis tabs and the relax data store now works.

The new() method is now for launching a wizard for analysis type selection.

Added a map to convert the analysis name in the savefile to that used by add_analysis().

The analysis tabs are now being reconstructed via add_analysis().

Removed some useless code from add_analysis().

A question dialog now appears before loading a save state if the GUI is not in the initial state.

This is just a warning that all data would be lost.
