TrigmuRoI: Make TrigMuonRoITool private
Make the TrigMuonRoITool
private. Having the ToolHandle in the
private
section doesn't make it a private tool. One needs to use the
constructor that takes a parent pointer.
In addition:
- Protect big block of DEBUG messages with a single if-statement
- AthenaMonitoring -> AthenaMonitoringKernel
- Delete old Changelog
