SMB/CIFS mount using OwnCloud logon credentials

Selecting 'SMB/CIFS Auto' in the mounts configuration allows an SMB/CIFS
mount to be configured that uses the credentials of the user logging in to
authenticate to the server.

Optionally, the username can be used as the share name, permitting home shares
to be dynamically mounted.
