Fixed the calls to filedialog.openfile() in the auto model-free protocol.

The cwd is now opened by default for each of the '+' buttons.

Converted to state_load() to use the relax data store.

The data store is first reset, and then the state loaded. For some reason, the text fields do not
update yet!

Deleted the sel_aic() and sel_bic() methods as they have been shifted to analyses.auto_model_free.

Renamed save_state() and openGUI() to state_save() and state_load() respectively.

The methods have also been alphabetically ordered.

Convert all the ref_noe*() and sat_noe*() methods to the new GUI design.

I.e. the relax data store is used, and comments and docstrings have been added.

Created a series of class variables to keep track of the hardcoded 3 NOE, 3 R1, and 3 R2 frames.

These will be removed once flexible addition and removal of analyses has been added.

Updated the sat_noe1() method to work with the new GUI design.

The relax data store is being used and commenting and a docstring has been added.

Fixes to the Analyses() class.

The corresponding XML element is now correctly created.

The Element name and description are now args to __init__().

The RelaxListType class is now far more advanced and can handle elements with to_xml() methods.
