Added support for getStats in screenshare's service. This works similar
to the getStats for video provider, and the information retrieved from
screenshare is added to the video information for cameras.
We now retrieve update information about active video peers, and calculates
download and upload rates. These rates are the sum of data transfered in
all video peers.
Screenshare stats is not being added to the sum, yet.
- Removed the connection-status history from the user list's gear
icon and now is opened by the connection-status button. Moderators will
render the same modal as before and viewers will only have access to their
own data.
- Added data-savings shortcut at the connection-status modal.
- Added websocket round-trip time.
Use the former Flash client avatarURL join param to replace the name
initials avatar from the user list, chat, waiting guests and connection
status list.
It is possible to define a defaultAvatarURL at bbb-web and enable/disable it
