Shifted the boolean selection operations of the generic_fns.selection module into two new functions.

These are the boolean_select() and boolean_deselect() functions. The change removes much duplicated
code which could be a source of bugs in the future.

Created the select.domain user function front and backend.

Created the Selection.test_select_domain_bool_or system test.

This is to better check the operation of the select.domain user function.

Created the generic_fns.domain.get_domain_ids() function.

This will be used in the GUI for domain related user functions.

Created the RelaxNoDomainError error for undefined domain IDs.

Created the Selection.test_select_domain_bool_and system test to check the select.domain user function.

This user function does not exist yet.
