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
