Added
- The `.cancel_add_or_edit()` method of `DAList`.
Changed
- The browser's use of dark mode is now remembered as part of the
session data, and screenshots in the Playground match the mode.
- Upgraded `cryptography` and `flask-cors`.
- When `docx template file` is used with `fields`, Jinja2 can now make
changes to objects in the interview answers.
Fixed
- Replaced `pycurl` with `requests` because it was causing problems
for the `.from_url()` method of `DAFile`.
- Pressing Tab to navigate to the CodeMirror editor now focuses the
editor appropriately.
- Problem with pushing to GitHub from Playground, introduced in last
version.
