check if the metadata passed in the create call is empty; raise an exception if the private key isn't found on the recording server; updated the deploy script using the ideas implemented on chef

improved the deploy script so if no parameters are passed, it will act as a recording server; if a text parameter is passed containing "mconf", the encryptor will be deployed

copied the entire record-and-playback module of BigBlueButton master (pre 0.81) to the v0.8 tag; the only file merged is record-and-playback/core/lib/recordandplayback.rb

insert the scroll bar on the chat automatically instead of grow the div indefinitely; little improvement on the deploy script for the recordings

integrated the video playback into master, but the whiteboard events playback, as well as the presentation playback, is not functional yet - it seems that the writing.js is broken on master, tried to fix it without success
