Draft merge 51-improve parameters

Browse Source 
There are some unsolved issues, like representing the mix of analysis+parameters
in a sensible way.
I think we should somehow represent each of the analysis tasks with a unique ID,
and it should contain the specific parameters used.

Right now results.parameters is a mix of a dict with global parameters and a
list with a dict of parameters per plugin.
