Insanely massive clean up of all of the Bieri GUI code base.

Not much code has been unaffected by this change. The changes include:

- Important fixes for the whitespace rule violations. There were identified by the
'scripts/code_validator' script. The number of spaces used for indentation was almost random and
hence impossible to work with. Spacing between functions was not following the 2 empty line rule.
Non-arg assignments with '=' sometimes had no space or 2 spaces. Comma separated elements (lists,
tuples, function args, etc.) often didn't have a space after the comma. A few tab characters were
being used whereas '\t' should have been used. There was trailing whitespace everywhere.

- All functions have been shifted to be before classes.

- All functions/methods have been alphabetically ordered. This is important to follow the code.

- Classes were not always capitalised.

- Removed the executable properties from gui_bieri/analyses/select_model_calc.py.

Shifted the target function initialisation into _target_fn_setup().

This will be shared by the calculate() method.

Removed the beta angle folding from the frame order module as it was failing.

Abstraction of the images and icon paths.

The module 'paths' has been created to hold hardcoded variables pointing to the image and icon
paths. All GUI modules now use this 'paths' module. Therefore if an icon or image needs to be
changed, on change to the 'paths' module propagates to all GUI elements (avoids code hunting when
modifying paths).

Import fixes.

Changes include comments added, alphabetical ordering, and removal of unused imports.

Fixed all the imports in the gui_bieri.execution package.

This includes fixing paths, removing many unused imports, alphabetical ordering, and general clean
ups.

Fixed all the paths to the GUI images.

Fixed the imports in gui_bieri.analyses.relax_control.

The module paths have been fixed for the new layout, the imports alphabetically sorted, and
whitespace fixed.

Fixed the path to the relax_16x16.png image.

Converted the 1st comment in the gui_bieri.relax_gui module into a properly formed module docstring.

Alphabetical ordering of the relax module imports.
