Allow mirroring individual webcams

Fix Typo in bbb-record

This patch fixes a typo in bbb-record causing problems by checking the
bigbluebtuuon user.

BigBlueButton already allows mirroring the users own webcam as a global
setting set by administrators. Users have no way of choosing this on
their own.

This patch turns this functionality into a user setting for all webcams.
Every camera menu now gets a “mirror” entry.

The global setting is still used as a default value, keeping the current
behavior as it is to not confuse users.

Mask output of which command

First version of a PeerTube player

Remove callbacks from mongo operations

Pulled HTML5 locales, Nov 27, 2020

Reduce server side logging

Add flag to enable/disabled custom heartbeat

Use INFO message as default for sending dtmf on call transfer

Instead of sending using rfc4733 standard, we use INFO message for all transfers
INFO message was used in older SIP.js version. Although this is not a standard for sending DTMF tones, this has more reliability (once it sent over TCP)
This might reduce occurrences of 1008

Don't warn about sip.js if sipjsHackViaWs=true

Removed string interpolation for server debug and verbose logs

Reduce delay for the first reconnection attempt of audio's websocket

This is the same behavior we used to have on older sip.js version code
By doing this we reduce errors when user try to perform join/hangup during an websocket reconnection

Added check for default stun.freeswitch.org

Do not trigger reconnect when ICE connection terminates before hanging up process is finished
