Added systemtest to black-list, if they depend on C-code module.

Improvements for the spectrum.error_analysis button in the spectrum list GUI element.

The user function is now launched as being modal so that the rest of the GUI freezes, and after the
user function is executed the relax controller window is show and scrolled to the bottom.

Modified the behaviour of the spectrum.error_analysis button in the spectrum list GUI element.

Now the subset argument of this user function will be pre-set to any spectra selected in the list.

Added path to other dataset with BFGS.

Added dataset which was produced with BFGS.

This shows, that gradient calculation is either wrong in relax, or in minfx.
This is only for minimisation.

It is also easily to see on the graphs.

Opened for the possibility to BFGS as minimisation methods.

Fix for scaling of parameters in bootstrap.

I cannot find the error, so a relax setup with BFGS will be setup.

Added a button for the spectrum.error_analysis user function to the spectra list GUI element.

This is placed after the 'Add' and 'Delete' buttons. The functionality could be improved by
presetting the spectrum ID argument to anything the user has selected in the spectrum list.

Another fix for the minfx version checking in the dep_check module.

The version_comparison() function has been created to perform a proper version number comparison by
stripping trailing zeros, converting the two version numbers to lists of int and comparing the lists
using the Python cmp() function. This will return -1 when the version number is too low, 0 when the
versions are equal, and 1 when the version is higher than the minimum.

Added scaling to the Jacobian matrix.

But something is very weird with the function values.
