Logging of score filenames

Currently when you use bash expansion, it is not possible to know if the correct score file goes into the correct place. For example, with a complicated bash expansion like:

bin/bob pad multi -e -pn 10 /idiap/user/amohammadi/swan/swan_{frame-diff-svm,lbp-svm-160,lbp-svm-64,qm-svm-160,qm-svm-64}/PA.F.1-{0,1,2,3,4,5,6,7,8,9}/scores/scores-{dev,eval} --legends frame-diff-svm,lbp-svm-160,lbp-svm-64,qm-svm-160,qm-svm-64

It can become complicated to know which files went where. The best thing is log these score filenames using the logging module.
