Fqq default is not floating

Now to make HiggsJPC workspace with fqq included use:

--PO=fqqIncluded --setPhysicsModelParameters fqq=0.0 (to set fqq as constant)
--PO=fqqFloating (to set fqq as floating with default range 0-1) can also optionally have --PO=fqqRange to change the range. 

Also means back compatible with previous version.
