Added one more iteration for the zooming optimisation of the frame order auto-analysis.

This is to improve the speed of optimisation when all RDC and PCS data is being used. The previous
iterations where with [100, 1000, 200000] Sobol' integration points and [1e-2, 1e-3, 1e-4] function
tolerances. This has been increased to [100, 1000, 10000, 100000] and [1e-2, 1e-3, 5e-3, 1e-4].
The final number of points has been decreased as that level of accuracy does not appear to be
necessary. These are also only default values that the user can change for themselves.

Expanded the CaM pseudo-ellipse test data frame_order.py optimisation script.

The optimisation is now implemented as in the auto-analysis, with an iterative increase in accuracy
of the quasi-random numerical integration together with an decrease of the function tolerance cutoff
for optimisation. The accuracy of the initial chi-squared calculation is now much higher. And the
accuracy of the initial grid search and the Monte Carlo simulations is now much lower.

The results of the new optimisation are included.

Expanded the CaM rotor test data frame_order.py optimisation script.

Constraints are now implemented in the frame order grid search.

This is useful for the pseudo-elliptic models as the cone theta_x < theta_y constraint halves the
optimisation space.

Removed a terrible hack for handling the frame order analysis without constraints.

This is no longer needed as the log-barrier method is now used to constrain the optimisation, so
that the torsion angle can no longer be negative.

Expanded and improved the docstring for the relax_disp.r20_from_min_r2eff user function.

This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/5957.

The documentation now covers a number of the uses for this user function. The text has also been
lightly edited. To fit all the text into the GUI user function window, the size of the dialog and
the text high settings have been changed.

Large improvements for the detection of cross-compilation on Mac OS X systems.

The tests for different architecture support now follows the ideas discussed in the post
http://thread.gmane.org/gmane.science.nmr.relax.devel/5785/focus=5820.

In summary, for each architecture a simple C file is created, compiled with 'gcc -arch xyz', and the
resultant binary file tested. To support 64-bit compilation on 32-bit systems, all previously
successful architectures are also included in the gcc command.

The change allows the 'ppc64' architecture to be reintroduced.

Fixed the docstring for the det_arch() method of the sconstruct script.

This is for the true cross-compilation detection on Mac OS X.
