The _build_doc() function now creates a dictionary version of _doc_args if it exists.

This will allows the GUI and other UI elements to easily obtain the argument descriptions.

The ALLOWED_MOL_TYPES list is now used for all the molecule docstrings.

This allows this list to change, and all documentation will be up to date.

Updated all of the molecule user function docstrings.

All select and deselect user function windows now use the get_title() base method.

Created the UF_base.get_title() method for setting wizard window titles.

The deselect.all() user function now uses this.

Removed the UF_base.setup() method as nothing is using it.

Updated all of the select and deselect user function documentation to be suitable for all UIs.

The 'change_all' flag in the select.read user function window is now also set to False.

This is the 'spin identification' to 'spin ID' change!

The previous commit was changing the default value of the 'change_all' flag in the deselect.read
user function window to False.

The spin_id_element() text is now 'The spin ID string'.
