Android: initial implementation of ownCloud provider.

This implementation can connect to a local server and browser its
contents, but cannot download and open the documents yet.

TODO:

* Download and open documents.
* UI to configure server, user and password.
* Implement filtering to show only the documents of the desired type.
* Improve error handling.
