- fix problem where only one user is able to join the voice conf. We are renaming the sip context which makes
   red5 not find it

 - call netstream.close() to stop the stream. Calling netstream.play(false) makes red5 look for a file to stream

bbb-record --check now checks if the IP address for a recording matches the value defined in bigbluebutton.properties

 - rename the api method names
 - cleanup

Add bbb-html5-client to labs
