Shifted the Uf_info singleton into the new user_functions.data module.

This will avoid a lot of circular imports.

Created a module for setting up all of the user function data.

This is just a test, so probably will not be permanent.

Created the Uf_info singleton class for holding all of user function data.

Created a number of special objects for the user function data storage.

Fix for the Base_value ResetChoices() method.

The recent simplification was failing as the ComboBox.Insert() method could not handle the position
being set to sys.maxint, unlike most other of its methods.

Big bug fix for the test suite!

One of the state system tests was removing the frame order analysis from the
generic_fns.pipes.VALID_TYPES list with a pop() call. But this change is permanent. So in the
later Bmrb.test_bmrb_rw GUI test, the GUI fails as this list is used in the pipe.create GUI user
function interface and it no longer matches the corresponding PIPE_DESC_LIST structure!

Created the empty user_functions package.

Creation of a branch for redesigning the internal structure of the user function.

The aim is to create a new package called 'user_functions' which will contain absolutely all
information about user functions, from documentation to icons to be used in the GUI. This package
will contain a special data structure which will be used by the different UIs to automatically
generate their interfaces to the user functions. This will significantly simplify the code base
and make it much easier to create user functions for all UIs simultaneously.
