try to speedup getrecordings, could reduce from 35s to 25s, but it's still not enough; need to better understand where's the bottleneck

Fixed audio connection problem. Maybe this timer made sense when WebRTC audio connection wasnt being transferred after echo check

Added to the default list of events the events triggered when a user
joins/leaves the voice conference and when shares/unshares a webcam.

replace font tag on formatted shared notes by the span style attribute; remove textformat tag; improve readability

changed the method of pack and unpack the encrypted format, from zip to tar, and making it by an external command instead of doing it in ruby (more efficient)

sanitize the parameters of resizeAndMoveSlide, so MeetingActor won't throw an Exception because of NaN

change attribute on bbb_webrtc_bridge due to a new version if sip.js, from iceGatheringTimeout to iceCheckingTimeout

Conflicts:
	bigbluebutton-client/resources/prod/bbb-deskshare-applet-0.9.0.jar
	bigbluebutton-client/resources/prod/lib/sip.js

add a menu next to the save notes button so the user can save both formatted or unformatted notes; create a new class WellPositionedMenu which will automatically position a menu next to a button or any other display object; cleanup

add the byte order mark for UTF-8 when saving notes, so it will be displayed properly in the browsers

Updated SIP.js to match master

We need to update the registered user's list when role and waitingForAcceptance change because reconnection doesn't trigger a userLeaving msg anymore
