This patch takes care of replacing the NSNotification events fired
from the AccountConfigurationManagerAdaptator by a delegation pattern.

Indeed, we only want the AccountsService to be notified of callbacks
coming from the daemon. NSNotifications fired from the NSNotification
default center are broadcasted events. We want to avoid them as much
as possible.

In order to achieve this, a protocol is declared on the Swift part of
the application.
Then, the Ring-Swift.h generated file will take care of exposing it to
the objective-c source code (thanks to the @objc annotation).

We need the pch file to be present to resolve UIKit and Foundation in
the generated Ring-Swift file.

The accountsService now registers itself to the
AccountConfigurationManagerAdaptator as the reveiver of its callbacks.

Because notifications are not used anymore at this time, we remove
the related files factorizing the notifications names.

This patch reorganizes the structure of the bridging between the Swift
client and the Daemon.

It isolates the code related to the account service. That's why there
is a renaming of the ConfigurationManagerAdaptor.
We want it to be specialized in what the account service can do.

The files meant to make the bridge between the client and the daemon
are now stored in a dedicated file in the project structure.

The broadcast by NSNotification posts is still used here.

This patch reorganizes the project structure to separate entities in
specific groups.
It also renames some files.

This is done to improve the separation of concerns of the components
of the project.
The renaming operation reflects the MVVM architecture that we will try
to implement.
