Upload folders

Currently people have to manually create folders inside folders and then upload files to them.

Make a feature which allows brs to upload a single zip folder to the website and the website will automatically create the file and folder objects and upload the files to onedrive.

However there is a major issue with this, currently a folder can only have either folders as its children or files as its children, so I have two ideas to solve this:
1. if a folder has both folders and files as its children then put the files in a seperate folder with some name (like the parent folder name itself). if a folder only has folders or files then its simple.
2. (check issue #171 ) if a folder can have both files and folders as its children, then doing this feature would be much easier ( I think)

Inizia leggendo l’issue #171 e tracciando il flusso di caricamento esistente del sito web, incluso il modo in cui vengono creati gli oggetti cartella e file e il modo in cui i file vengono inviati a OneDrive. Determina se sono supportati elementi figli misti di file e cartelle oppure definisci il comportamento per le cartelle separate. Il lavoro è completato quando un singolo caricamento ZIP ricrea le cartelle, carica i file e gestisce entrambe le strutture di cartelle in modo coerente.

Scritto dal modello di indicizzazione a partire dal testo della issue.
