Up until now we relied on implicit loading of middlewares and reducers, through
having imports in each feature's index.js.

This leads to many complex import cycles which result in (sometimes) hard to fix
bugs in addition to (often) breaking mobile because a web-only feature gets
imported on mobile too, thanks to the implicit loading.

This PR changes that to make the process explicit. Both middlewares and reducers
are imported in a single place, the app entrypoint. They have been divided into
3 categories: any, web and native, which represent each of the platforms
  respectively.

Ideally no feature should have an index.js exporting actions, action types and
components, but that's a larger ordeal, so this is just the first step in
getting there. In order to both set example and avoid large cycles the app
feature has been refactored to not have an idex.js itself.

> playinline attr needs to be set to true to stop local video from playing in full screen mode in Safari on iOS.
> This applies to the local video thumbnails and the camera previews from the device selection menu and video preview button

The lobby feature adds the possibility to lock a meeting and only allow people in after virtually knocking and going through formal approval

Update userSelectedAudioOutputDeviceId and userSelectedAudioOutputDeviceLabel when a new speaker is selected from the audio settings popup menu

Pass the real deviceId to gUM instead of 'default' for Chrome to return the correct media stream

* fix: Fixes using token with no user context.

* feat(moderated): Adds option to add moderated rooms and subdomains.

When a user joins such room or subdomain in order to be a moderator needs to provide a valid jwt token for that room.

* squash: Renames function.

* ref: Removes filtering jicofo setting owners.

This will be disabled on jicofo side and will greatly simplify logic.
Also check the checks to avoid jwt for main domain to access subdomains and the other way around.

* fix: Skips allowners logic for admins.

Use a dimensions detecting root component. The Dimensions module does not
measure the app's view size, but the Window, which may not be the same, for
example on iOS when PiP is used.

Also refactor the aspect ratio wrap component since it can be taken directly
from the store.

Last, remove the use of DimensionsDetector on LargeVideo and TileView since they
occupy the full-screen anyway.

Fixes PiP mode on iOS.

We were only using a couple of utility functionss to parse tokens, not to
validate them in any way.

This breaks the mobile deeplinking page
This reverts commit 532dadb245.

This update opens links in the full body of the window so deeplinks will work on iOS Safari when using the external API in an iFrame.

* The prejoin page always displays the 'join without audio' option.
* The join button will be disabled if there is no input.
* Fix some CSS for the case when the user is not anonymous.

The ocnfig is not overridden early enough.

It is now possible to change the sender video quality for p2p calls as well

Avoid importing components, which are not yet implemented on mobile.
