Created the GUI test base method execute_uf() for executing a user function.

This is an interface which will massively simplify the creation of GUI tests, so that they can be
almost the same as normal relax scripts. This will allow for the porting of most of the system test
scripts into GUI tests. This however requires the use of the new wizard page element_*() methods
to create the GUI elements.

The bmrb.citation GUI user function now uses the new wizard page element_*() methods for the GUI elements.

Created a new wizard element for inputting integers.

This will be used for user function args which should be integers. This is based on the string
element. The wizard page element_int() method creates the element from the wizard_elements.Integer
class.

Created a new wizard element for inputting strings.

This will be used for user function args which should be strings. The wizard page element_string()
method creates the element from the wizard_elements.String class. This class inherits from
wizard_elements.Base_value which contains most of the executable code.

Created the Bmrb.test_bmrb_rw GUI test.

This incomplete test is based on the bmrb_rw.py system test script.

Completed the GUI interface for the bmrb.citation user function.

Fix for the bmrb.citation user function documentation.

The 'type' argument was not being described.

Debugging print out removal.

Created a new wizard GUI element for lists of lists of strings.

This is similar to the list of strings GUI element, but has been extended for list of lists. It is
now used by the bmrb.citation user function.

The element_string_list() wizard method now has all arguments converted to keyword args.
