Bug fix - 'local_mf_model' should have been called 'local_tm_model'.

This problem was identified by Michael (http://gna.org/task/?6847#comment44).

Corrected import of number of Monte Carlo simulations from relaxGUI settings.

Popup appears after pushing relaxGUI controller kill button to make sure users would like to kill current session.

The relaxGUI controller cancel button is replaced with a kill button.

As python does not allow to selectively kill running threads, a kill button in the relaxGUI controller was introduced, which kills the program.

The output filename also consists of the frequency.

Outputfiles after Rx curvefit will be saved such as: r1.600.out.

Name of the results file in Rx curvefitting is set.

Outputfiles will be named r1.out or r2.out.

More keywords for automatic Rx fit are introduced.

Keywords for results directory, pdb file and unresolved file are added.

Number of Monte Carlo simulations set in the settings dialog is assigned for relax_fit.py calculation.

relaxGUI creates a dummy file for unresolved spins that will be used in relax_fit.py

The relaxGUI controller updates its progress bar using informations from the status singleton during model-free analysis.

Currently, there is a maximum of iterations set for models 1 - 5. This also has to be set in the dauvergne_protocol.py script. Edward, what do you think about limiting to 20 iterations?
