Follow-up to 4bbae6e17
We're now using Zotero.HTTP.request(), which does its own checking for
security errors, so there's no need to do WebDAV-specific checks (though
we could consider checking for Zotero.HTTP.SecurityError and showing
more specific messages, since a self-signed certificate is more likely
in the case of WebDAV).
If a server returns an invalid HTTP response (e.g., Content-Encoding:
gzip with a plaintext body, a.k.a. NS_ERROR_INVALID_CONTENT_ENCODING)
but we can still parse a 4xx or 5xx HTTP response code, use that for the
XHR status, since it might be enough for what we need to do (e.g.,
verify a 404 from a WebDAV server). This fixes a current problem with
Box [1].
Also fix a "msg is not defined" error when the XHR status is 0 but the
SSL connection is fine and include the channel and response status on
the UnexpectedStatusException object (though both of these would now
only happen on an invalid 2xx response, when the XHR status would remain
as 0).

purgeDataObjects(), which runs at the beginning of the sync process,
uses transactions, and those can fail after the default wait timeout if
there's another active transaction. Instead, check explicitly for
another transaction and, if there is one, display a nice message and
wait for it to finish. This isn't foolproof, but it should reduce the
frequency of "operation timed out" sync errors. (Avoiding all long
transactions would be a better solution.)
If a transaction took over 30 seconds and another transaction timed out
waiting for it, the second transaction would reset the notifier queue,
but if the first transaction then tried to queue an event, it would fail
with this error and roll back. (It would be nice to figure out why
transactions are taking over 30 seconds, though.)
- Updates /saveItems and /saveSnapshot to take a sessionID
- Provides a list of editable collections in the current library
- Adds an /updateSession method that takes a sessionID and updates the
collection and tags of any items saved via that operation (and changes
the currently selected collection)
Cross-library changes are not yet supported
This is a simplified version of the fix from #872. Unlike the proposal
in #36, this doesn't require all child items to be selected, since in a
search some children might be grayed out. If the child of an unselected
parent item is included, the drag isn't allowed.
Closes#36
"Delay citation updates until manual refresh" would be fine in the doc
prefs, but "until manual refresh" is a bit too awkward for the prompt.
Instead, go with @rmzelle's suggestion from #1242 of referring to
"automatic citation updates", and invert the checkbox.
