[Rivet] Rivet 2.5.1 installation in Genser

[Andy Buckley]

Hi Genser,

Yesterday we released YODA 1.6.3 and Rivet 2.5.1. Can we get these 
installed in the Genser/LCG collection asap, please, so ATLAS and the 
other experiments (reps CC'd) can pull them into software builds? Thanks!

Looking at the current LCG_* repos it seems that Rivet 2.5.0 was only 
installed in LCG_84. So I guess we want the same for 2.5.1 (+ YODA 
1.6.3), but probably also LCG_85. Do the experiments want installation 
in other LCG collections, bearing in mind that both YODA and Rivet now 
need a C++11-compatible compiler?

Thanks again,
Andy
