Major fixes to the raw-data simulation. The ADC samples and signal width are added to the raw-data stream. The trigger flags are stored in the digits tree user-info and then propagated to the raw data and esd. The digit class is updated by removal of unneeded members. Some code clean-up as well. We need one more step before in the reconstructor in order to declare raw-data and digits sim/reco are completely equivalent. This step is to move the code from ConvertDigits to Reconstruct method.
