Show full backup location, particularly for WebDAV

[t-m-w]

As I've been testing things, I have a device which is set to use WebDAV and a particular server, but I cannot remember the full backup location it's set to use, and I cannot view it. All I can see in the Seedvault settings preference for Backup location is "WebDAV [hostname]". Being able to see the full path would be useful for me in this case.

(Also being able to see the username would be useful, but that's a bonus.)
