Bugfix ext. fcts with z+ up

• Bugfix: Since v1.10.5, one can provide depth also in decreasing order. Internally, all parameters are reversed then. However, parameters in user-provided func_eta and func_zeta were not reversed, so far the user had to take care of this (and hence define them differently to the rest, which is a bug really). Now any provided parameter in the res-dict is also reversed. If verb>2, these parameters are finally also printed.

• Gallery: New example IP and VRM, based on a notebook from @orerocks.
