Import fixes for the relax controller window.

Renamed the 'relax_control' module to 'controller'. There is no need to prepend 'relax_' to this.

Renamed the Log_window class to Controller, as this dialog will be more than a log window.

Shifted the relax_control module down back into the gui_bieri package.

This is a GUI element that is independent of the specific analyses. The analysis specific code can
be shifted into the modules of gui_bieri.analyses, and the threads also started from there. This
window can be initialised in the main GUI class and then shown by the analyses' execute methods.

Removed a few args from gui_bieri.analyses.relax_control.start_modelfree().

Renamed and shifted exec_model_free() to automatic_protocol_controller().

This is to better distinguish between the names exec_model_free(), start_modelfree(), and
start_model_free().

exec_model_free() now synchronises the frame data to the relax data store.

Changed the calls to gui_bieri.execution.calc_modelfree.start_modelfree().

The 'self' arg has been removed (this should never be passed into functions). The args have also
been converted to keyword args.

Removed a debugging print out.

Shifted the selection variable from the global namespace into the class namespace.
