There is no need for setting the availability of desktop sharing anymore. It can
now be detected on the spot.

The reson for the previous code was that way back when browser extensions were
needed, it was possible to start a conference without desktopo sharing support
and get it afterwards. This is no longer the case.

This fixes an issue where lastN is not bumped to 1 on an audio-only client when a screenshare source is added to the call.

Take into account the start muted values stored in local storage.

Through several avatar work iterations it's no longer used.

Use fetch(), which gives us better control over headers.

This change serves 2 purposes:

- (Hopefully) make the recent list entry options easier to discover
- Remove the (now unmaintained) swipeout dependency

Always attempt to discover the configured STUN/TURN servers.

This fixes the issue where the local preview appears muted when presenter camera is turned on and then off while screenshare is in progress.

Decode URLs using punycode when rendering, so when http://ebаy.com is sent
we render http://xn--eby-7cd.com/ instead.

It doesn't play well with webpack and it's babel config
and I couldn't find a way to make it work.

Allows to adjust thresholds which control the video quality level
in the thumbnail view.

Changes the default behaviour to request the SD (360p) resolution only
when the thumbnails are at least 360 pixels tall and the height of
720 is required for the high quality level.

The thresholds can be configured with the 'videoQuality.minHeightForQualityLvl'
config property. Check the description in the config.js for more details.

* Adds a dropdown indicator which displays the status of the internet connection.
* It uses the same data as `https://network.callstats.io`.
* The algorithm for the strings displayed to the user is also the one used on `network.callstas.io`.

Does not skip passing jwt even when malformed to allow getting the error, terminating the connection and showing the warning. We were not passing jwt when malformed and were successfully joining a conference for deployments where no token is allowed.

Add a config option with the default value of 2, which will cap the max recv video quality to SD if there's more than 2 participants in the conference while in the tile view mode.

Adds 'lastNLimits' config value which allows to define last N value per number of participants.
See config.js for more details.
