* Insert a new 'set log level [level] command on the console'

* The primary immediate use is to provide a means of temporarily reducing log output on the console when executing console commands
* Changing the log level on the console is not permanent and does not affect the log information being put into OpenSim.log
* This could have been done by putting in a threshold level on the Console appeneder in OpenSim.exe.config and implementing config watching in the code.
* But I think that it's a little more user friendly to make this doable via the console.
