Shifted more of the relax_gui.py code into the automatic model-free module.
This code was originally deleted as it was not thought to be part of the model-free panel. The
names such as:
- label_2_copy_copy_3_copy_copy_copy_copy_2
- label_2_copy_copy_copy_2_copy_copy_copy_copy_1_copy
- results_dir_copy_copy_copy_1_copy_2
etc. are confusing and will be eventually renamed as they will be in the scope of a single method and
nowhere else.
