PoldiFitPeaks2D should have an option to tie profile parameters

[MichaelWedel]

This issue was originally TRAC 11887

In the original POLDI analysis software, there was an option to use Pseudo-Voigt profiles for the peaks. The mixing parameter that determines the ratio of Gaussian and Lorentzian for all profiles was tied, so that all profiles have the same shape. For calibration the case is similar, there is a "global" parameter that is the same for all peaks.

I would like to add an Input-property to PoldiFitPeaks2D, where the user can specify a list of parameter names that should be identical for all peaks. Since the profile parameters of functions are documented in the wiki, it's relatively easy to find out. In the workflow algorithm defaults will be set for the available functions so this is hidden from the "average user".
