TRT cosmics event phase
The calculation in beginRun() of the average T0 is moved to a new Condition Algorithm (instead of just calculating it once and for all is in the current master).
TRT_CalDbSvc is replaced by a private TRT_CalDbTool everywhere in the cosmics reconstruction where this was possible. That goes also for TRT_StrawStatusSummaryTool.
The corrections for HT and ToT that were recently introduced for Argon gas in TRT_DriftCirleTool are now also in TRT_DriftCircleToolCosmics.
