If the beginAddPeople delegate method is implemented, and they haven't been
explicitly set to NO, they willbe YES.

We just call the parent class' method, so just get rid of it.

While having configuration-specific AppIcons may be of questionable use,
I'm more interested in using the Debug version for enterprise
distribution and the Release version for AppStore distribution.

JitsiMeetViewListener is an integral part of the public API of Jitsi
Meet SDK for Android. Utilize it in the Debug configuration of the Jitsi
Meet app for Android in order to increase (1) awareness of API breakages
and (2) API coverage.

The same goes for JitsiMeetViewDelegate in Jitsi Meet SDK and app for
iOS.

On iOS, if the app is closed the startup options are only passed as the
`launchOptions` dictionary of `applicationDidFinishLaunching`. Thus add a helper
method to be called from there by embedding applications so we can copy that
dictionary.

Before, Jitsi Meet (the app) would only link with JitsiMeet.framework, which in
turn embedded WebRTC.framework. While possible, Apple doesn't allow apps with
nested frameworks to be submitted to the store. Now the app will link with
WebRTC.framework directly so there is no framework nesting.

A potential improvement here is to build WebRTC as a static library so it can
then be embedded in JitsiMeet.framework and completely hidden from the app.

1. Aligns the project structure of Jitsi Meet SDK for iOS with that for
   Android for better comprehension.

2. The command `react-native run-ios` uses the last Xcode project or
   workspace in the list of these sorted in alphabetical order. Which
   limits our freedom in naming. Thus having only an Xcode project in
   the root directory of the iOS project structure gives us back the
   freedom in naming.

3. Allows the Podspec to work for the app project in addition to the sdk
   project because we need Crashlytics in the app which is integrated
   via Cocoapods as well.

4. Further removes references to JitsiKit in the source code for the
   sake of consistent naming.

Ladies and gentlemen, allow me to introduce you to Jitsi Meet SDK for iOS, the
mobile SDK which powers Jitsi Meet.

The goal is to encapsulate the entire React Native app into a framework / SDK
and offer an API for native (ObjC or Swift) applications to embed the Jitsi
conferencing experience.

While React Native can be embedded in native applications, I don't think it was
designed to be embedded as part of a framework, hidden away from the application
using it. This surfaced as a number of issues which had to be addressed
specifically due to our use-case:

- Universal / deep linking needed to be wrapped to avoid the embedding app from
  linking with RN.
- The bundle URL had to be manually constructed, since RN considers that all
  resources are in the main bundle, but in case of a framework that is not the
  case.
- Custom fonts had to be manually loaded, since UIAppFonts doesn't work on the
  framework's Info.plist file.
- The RN packager has to be manually triggered since the React project will no
  longer do it for us.
- Custom App Transport Security rules were added since the builtin way to do it
  modifies the framework's Info.plist, which is useless in this case.

At this stage, the Jitsi Meet application is just a small single view
application which uses the Jitsi Meet SDK to create a single view which
represents the entire application. Events and external conference handling are
forthcoming.

It will render as white in dark backgrounds. This is what FaceTime does and what
we already do on Android. The problem with the default look (black text) is
noticeable in audio only mode, since the background is dark.

Now that Apple have approved build 1.3.204 for release in the App Store,
the short app version needs to be incremented; otherwise, no new builds
can be uploaded to TestFlight and, respectively, for release in the App
Store.

When the audio-only mode is enabled, turn on the proximity sensor to dim the
screen and disable touch controls when there is an object nearby.

Now that Apple have approved build 1.2.199 for release in the App Store,
the short app version needs to be incremented; otherwise, no new builds
can be uploaded to TestFlight and, respectively, for release in the App
Store.

iTunes Connect/TestFlight requires these now and is not satisfied with
empty values anymore.

Now that Apple have approved build 1.1.185 for release in the App Store,
the short app version needs to be incremented; otherwise, no new builds
can be uploaded to TestFlight and, respectively, for release in the App
Store.

Simplify the source code (with the idea that source code which does not
exist does not have to be maintained).

Additionally, apply modifications to have the source code comply with the coding
style.

Overall, prepare saghul:audio-mode for merge into jitsi:master.

Now that Apple have approved build 1.0.178 for release in the App Store,
the short app version needs to be incremented; otherwise, no new builds
can be uploaded to TestFlight and, respectively, for release in the App
Store.

The launch screen appears not centered and/or clipped on certain
devices. Unfortunately, I cannot reproduce it when I deploy the app to
devices and Simulator from Xcode 8.1. It may (or may very well not) be
that the Xcode version matters and the enterprise build server does
appear to use an older Xcode version.
