Fix for the relax controller SplitIO() setup for logging and teeing modes.

The SplitIO() usage is now disabled for the test suite. This prevents a doubling of the print outs
in the GUI tests. The problem was introduced at r15843 with the accommodation for the logging and
teeing modes with the GUI.

The relax data store is_empty() method now only prints to STDERR if the verbosity flag is set.

The GUI test base execute_uf() method now only sets an arg if the arg has a corresponding GUI element.

Missing import causing all GUI tests to fail.

Edited all the module docstrings in the user_functions package.

Split up the gui.wizard_elements into a number of modules in the new gui.input_elements package.

The user function GUI page arguments are now updated after execution of the user function.

This allows ComboBox lists to be dynamically updated, and is useful for when the user clicks on
'Apply'.

Fix for the clearing of the ComboBox version of the Value GUI element.

The ComboBox text is now reset to '' as well, to clear out the previous selection which may no
longer exist.

Created a system test Mol_res_spin.test_residue_delete() demonstrating a failure of the user function.

Deleting the first residue removes the entire sequence!

Changed the behaviour of the generate_spin_id() and generate_spin_id_data_array() functions.

This is a large change affecting many parts of the code base. The problem that this solves is the
incorrect usage of the '&' character in spin IDs, tripping up on the powerful Selection object of
Chris MacRaild.

For example, the spin ID ':2&:Glu' cannot be correctly handled. This actually matches all residues
with the number 2, and all residues with the name 'Glu'. It is very strange that this has not been
noticed before!
