Sync Phone to FTP

The goal of this application is to enable you to sync folders on your phone to an FTP server.
* The Folders will be synced recursively
* The pictures will be synced with their full size
* You will get a notification about how much files have been synced and when the sync has finished.

In the first version, you trigger the sync manually. The folders that will be synced is chosen by you manually.
The FTP server is an easy service that can be deployed really in each home on the internet router for example. By doing so, you can configure the home FTP in this application and each time you connect to this router, you can run the manual sync.
