Update for Version 6

Version 6 was not starting on various computers. This is now corrected.

Additionally, the following improvement have been made:

The pulse profile creation now separates between the data array center wavelength and the wavelength of the profile. Thus, if for instance, the wavelength of a profile is varied during a parameter variation, the data array can be kept unchanged.

A previous error that did not allow to load a BPF file was corrected.
