* WIP adding whiteboard special user access test spec

* Adds additional user whiteboard access test spec to whiteboard.obj.js

Setting this as default to prevent bad UX: device selector is currently small
for mobile devices

This could be added as a config in future

By default this is set to true, allowing users to dynamic change audio devices
Fixed a few linter warnings

Allow listenonly users to change output devices
Fixed dynamic audio device change for firefox
Fixed shortcuts for audio join/leave
Show (with a bold font) the current selected device
[performance] Prevent calling mediaDevices.enumerateDevices every time we render
the selector. This adds a delay (~200ms, on my chrome setup) to render this component
[performance] Do not call enumerateDevices to search for new devices, instead we listen on mediaDevices.deviceChange event
Small refactoring and fixed a few errors that were being throw in browser's console
Fixed device selection when this is done in audio-settings modal
Fallback to default device when current device is removed
Truncate device name length
Renamed "Input","Output" labels to "Microphone","Speakers", respectively
Update eslint rule for accessKey

 - 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.

If the presenter gets changed while the user kept the getDisplayMedia browser picker open, accepting the getDisplayMedia prompt might get the previous presenter´s client-side state inconsistent as if they were sharing. The screen sharing is a no-op though

This adds a check after gDM resolves to see whether the user is still the presenter; if they aren`t, just clean up the gDM stream and make it a full no op

If created, mutedalert will crash client when trying to access inputstream
which is not yet ready.
