Add experimental "slow frames" stat, available in "show stats" and via the monitoring module.

This increments a SlowFrames counter if a frame takes over 120% of maximum time.
This commit also introduces a generic OpenSim.Framework.Monitoring.Stat which is available to any code that wants to register a statistic.
This is more granualar than asking objects to create their own reports.
At some point this will supersede earlier IMonitor and IAlert facilities in MonitoringModule which are only available to scene code.
