Implement running alpha_s into the FeynRules interface.
Implement running alpha_s into the FeynRules? interface. A potential caveat is the possible appearance of alpha_s in derived parameters; several remedies might exist for this case:
- forbid and trap in the interface (easy).
- work around in the interface by automatically moving derived parameters to the model glue code (difficult as this would require tracking the interdependencies of the different parameters)
- make WHIZARD recalculate the derived parameters when changing alpha_s and communicate them to the glue (feasible, but is this desired?)

Implemented in branches/speckner/feynrules_lab with r1891 and r1892. A change in \alpha_s triggers the reevaluation of selected derived parameters (per default \alpha_s and g_s if they are derived) and of all couplings depending on them.
