Spacing fixes.

Documentation improvements for the back_calc_I() function of the relax_fit C module.

Converted the Py_BuildValue() calls to PyFloat_FromDouble() in the relax_fit C module.

This doesn't change much.

Improved the Python and C documentation of the functions of the relax_fit C module.

Shifted the C array creation to the relax_fit C module header.

The params, values, sd, relax_times, and scaling_matrix C arrays are now declared and allocated in
the header file rather than using malloc() calls in the setup() function. This is to attempt to
remove a memory leak. The arrays are now of fixed length and reused for each setup() call. These,
as well as the other variables declared in the header are no longer declared in the functions.

Increased the maximum number of relaxation times for the relax_fit C module to 50.

Removed an unused declaration in the relax_fit C module setup() function.

The relax_fit C module setup() function now uses the Py_RETURN_NONE macro to terminate.

This macro does exactly what the old code does anyway.

Clean up of unused headers and declarations in the exponential curve C module.

Changed the 'Execute relax' button in all analyses in the GUI to 'Execute analysis'.

It makes no sense to execute relax as relax has been executing during the analysis initialisation
and the user setting up all the data for the analysis. This is a remnant of ancient design of
Michael Bieri's GUI being a separate program to relax, which would execute relax with the click of
this button.

Restored the Py_INCREF() function call in the relaxation curve-fitting C module.

This was deleted at r12632 along with Py_XDECREF() and Py_DECREF() calls. The absence of a
Py_INCREF() function call causes the module to crash the Python interpreter under certain
conditions. The problem was found in the relax_disp branch.
