* Show server response as error message in put saver I'd like to use this on Tiddlyhost so users can get more informative error messages if the put save fails for whatever reason. This would make the put saver a viable replacement for the legacy upload saver, which is what Tiddlyhost uses currently. I'm not sure what standard WebDAV servers do, but I would guess they don't provide any response body for put requests, and hence this patch would have no impact for a standard WebDAV server. (That said, it would be a good idea to test it to make sure there aren't any unexpected regressions for WebDAV or other put saver compatible services.) * Access http response status directly in put saver There's no need to extract it from the error string created inside tw.utils.httpRequest if we can get it directly from the xhr object. * Add 'Save starting' notification for put saver There are two related changes here: 1. Add a 'Save starting' notification for the put saver, similar to the upload saver. Not sure if it was intentionally omitted for the put saver, but it seems reasonable to have the two be consistent. 2. Send the 'Save starting' notifications in both upload and put save right before the actual request is sent. While testing I noticed that the save might have failed before the "Save starting" notification appeared which doesn't seem useful.
