This mostly gets ZFS file syncing and file conflict resolution working
with the API sync process. WebDAV will need to be updated separately.
Known issues:
- File sync progress is temporarily gone
- File uploads can result in an unnecessary 412 loop on the next data
sync
- This causes Firefox to crash on one of my computers during tests,
which would be easier to debug if it produced a crash log.
Also:
- Adds httpd.js for use in tests when FakeXMLHttpRequest can't be used
(e.g., saveURI()).
- Adds some additional test data files for attachment tests
Fix a couple cases of lost text field focus after an edit, including
focusing of the Title field after using New Item when a field is already
being edited and has a changed value.
Also, in tests, select My Library and wait for items to load when using
the loadZoteroPane() support function. We could add a parameter to skip
that or move it to a separate function, but the code to detect it is a
bit convoluted and it's a prerequisite for many tests, so it's handy to
have a function for it.
