Cleaned up in the naming of the histograms

Still issues with the phi value from DTChambPhiDigis
Added histogram with number of genMuons perEvent
Cleaned up the BuildFile to run scram b without warnings
Included DTTrigTest module from L1Trigger/DTTrigger package, which is able to print detailed information
on all DT Systems starting from the BTI
Adapted the DataAggregatorFile to include the DTTrig module and to provide a DT config record for it
