Summary:
- Rather than translate from moment format to that of bootstrap-datepicker, use
the customization methods to format datepicker dates using moment directly.
- Fix issue with parseDate() when format includes tokens like Mo or Do
- Fix issue in parseDateTime() that could produce an off-by-one error in date
depending on local timezone.
- When opening DateEditor, show AltText value if present.
- Add crossorigin=anonymous to scripts that were missing it (including
bootstrap-datepicker), to ensure that errors from them are reported properly
rather than as 'Script error.'
Test Plan:
Added test cases to parseDate() test for low-level fixes; added a
browser test for the fixed DateEditor behavior.
