add number of regulated hits in benchmark

[mlocardpaulet]

Hi,

in the benchmark output, we can find a lot of proportions relative to the output of the PolySTest such as:
propDiffRegPepWrong0.01.FDR_PolySTest 2 vs 1
propDiffRegPepWrong0.05.FDR_PolySTest 2 vs 1
propDiffRegWrongIDProt0.01.FDR_PolySTest 2 vs 1
propDiffRegWrongIDProt0.05.FDR_PolySTest 2 vs 1
tFDRPep0.01.FDR_limma 2 vs 1.tFDR
tFDRPep0.05.FDR_limma 2 vs 1.tFDR
tFDRProt0.01.FDR_PolySTest 2 vs 1.tFDR
tFDRProt0.05.FDR_PolySTest 2 vs 1.tFDR
tprPep0.01.FDR_limma 2 vs 1.TPR
tprPep0.05.FDR_limma 2 vs 1.TPR
tprProt0.01.FDR_PolySTest 2 vs 1.TPR
tprProt0.05.FDR_PolySTest 2 vs 1.TPR

I would really like to also have the total number of hits at the statistical FDR thresholds 0.01 and 0.05. This would be useful to put these proportions in perspective.
