[Rivet] Update to ATLAS Rivet routine

[Hendrik Hoeth]

Hi Andy,

Thus spake Andrew Pilkington (Andrew.Pilkington at cern.ch):

Thanks, we will put that into Rivet.

No, that is not possible. One reason is that technically it's impossible
to delete things from the internet. And the other, maybe even stronger,
reason is that ATLAS_2012_I1094568 was added *after* the last release,
so it's not even in there.

Cheers,

    Hendrik
