[Rivet] Many empty bins in refdata for JADE_OPAL_2000...

Hi Holger,

I suppose that's because it's on Hepdata that way (but please confirm). 
You mean just some bins, not whole distributions, right?

Thanks for volunteering, but if there are no serious drawbacks of the 
zeros, I would suggest not to, because 

1) We shouldn't deviate from Hepdata without need.
2) (Existing) AIDA files from the existing Rivet versions can't be 
plotted together with new ones then because the binning has changed.
3) Some of the bins without reference data might still be filled by 
(different) Monte-Carlo runs and thus might be useful for comparison.

Cheers,
Frank
