Subject: [PATCH] WebdavRepo: store attachments

Tested with a webdav server to confirm that attachment and its parent
directories can be created.

Caveat:
- The attachment: link cannot be resolved. Because this link currently
only resolves to local files, it cannot deal with remote files (like
webdav). To handle remote files, need additional changes to download
and cache the remote files.
