Potential bug in forward jet selection

[zucchett]

Even if i don't use the framework anymore, Deborah spotted a potential issue related to the jet ID in the JetsNtuplizer class:

The problem lies that the abs(eta) is computed, and not fabs(eta) as it should, leading to some dangerous approximation in the output. It may also depends on the C++ compiler.
