allow leds to be disabled after config loaded
Merge remote-tracking branch 'upstream/edge' into working
Merge branch 'working' into network
initial conversion of telnet to a class
renamed network stresam to callback stream
Switched over to passing a stream per connection
modified httpd to use that scheme too, still needs to route command to correct connection
telnet now accepts multiple connections
Make sure no crashes due to output to a closed stream on network, both telnet and webserver
Added use counts to the callback stream to keep it around until all commands are drained from command queue
