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!

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.

Initialized merge tracking via "svnmerge" with revisions "1-15903" from

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.

Simplified the wizard_elements.Base_value ResetChoices() method.

This is an attempt to fix some racing conditions under wxGTK, triggered in the test suite.

Fix for the align_tensor.fix user function caused by recent changes.

The tensor checking code was not suitable for this function and needed modification.

Updated the generic_fns package __all__ list for the 'pdc' to 'bruker' module renaming.

The Bmrb.test_bmrb_rw GUI test now uses the base execute_uf() method for the pipe.create call.

This is part of the simplification of the user function interfaces.

A number of the pipe GUI user function front ends now use the wizard page element_*() methods.

This is to simplify the code base.

The scons 'install' target now creates both *.pyc and *.pyo files during installation.
