Subject: * 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.
