Unified log to screen in reconstruction chain

The current reconstruction chain (in macro/run/run_reco.C) comes with tons of screen log output for each single event. For application to real (mCBM) data, this is not practical. The tasks were redesigned such as to give one line log output per timeslice in LOG(info) mode. Other output has been shifted to debug log level or lower.

The functionality of the reco tasks was not touched.

Missing is still CbmRichReconstruction, which must first be made suitable for run event-by-event.
