Add WebDav protocol as a new data source (like the SD Card is one)

WebDav is an IETF open standard protocol to sync files in your cloud, see ( http://en.wikipedia.org/wiki/WebDAV and http://www.webdav.org/ ).

There is a famous server implementation in PHP called SabreDav, used in the yet more famous software: Owncloud.

I've imagined that a web storage could be mounted as a new data source in Ubuntu Touch, as the SD Card reader is one of them. With a correct configuration interface, some folders could have a local cache (download all the elements).

This way for example, the camera app would be able to store the pictures locally in this source and sync them over the network once it will be available.
