Another round of fixes in order to use the event specie in the QA. The procedure is the following: 1. The QA data maker gets the event specie as defined by AliRecoParam class. 2. If the detector's reco-param object has different event specie the previous value is overwritten and QA uses the specie defined by the detector. If the event specie from AliRecoParam and the detector's event specie are both set to default, the QA will not fill any histograms. Therefore the detectors should properly implement and put in OCDB at least one reco-param object (there should be also one and only one default object) with event specie set to low-mult, high-mul, cosmic or calibration specie. The changes were prepared and tested by Yves.
