[Rivet] useInvisibles

[Andy Buckley]

I think we need to revisit the jet config interface for the next release 
-- with all the analyses that I know are in preparation and this 
mismatch becoming more obvious by the minute we're clearly going to want 
a 1.6.0. We can look into this when I'm down in Durham in a week or so...
