1) Fix in tracking condition pattern definition
2) ITS in the Config.C redefined for 20x20 pixels with 3*0.3,4*0.5% X/X0 layers
The module has 4chips with 13(X)x15(Z)mm active zone each, 2mm dead zone on the
readout side and 50micron dead zone around.
3) Regenerated itsupcdb.tar.gz with corresponding MakeITSUSimuParam and
MakeITSRecoParam tuned for PbPb reco (for 20x20 pixels diagonal clusterization is off)
