Docassemble

Added
- The `enable playground` Configuration directive.
Changed
- The behavior of the `label` option of `list collect` no longer
prints text before `1.`, `2.`, etc. Now the `label` supplies the
whole label for the item, and it can include the number by way of
the index variable.
Fixed
- The `list collect` feature raised an exception when the field
definition included Mako substitution.
- Non-required upload fields were creating zero-byte files on some
servers.

Changed
- The syslog-ng server is now started after the web server.
Fixed
- Unhelpful error message when there was an interview parsing error.
- `DAStaticFile` objects not being included in DOCX files correctly.

Added
- The `administrative interviews` Configuration directive
- The `sessions are unique`, `required privileges for listing`, and
`hidden` specifiers under `metadata`.
Changed
- The `words` system no longer uses code names like `pdf_message` and
`save_as_multiple`.
- The `required privileges` specifier under `metadata` now prevents
users without a valid privilege from starting the interview. The
`required privileges for listing` now controls whether the interview
is listed under `/list`.
Fixed
- Passing an asterisk in a list to Flask-CORS resulted in a regular
expression error.
- Not all Flask packages accept integers as the
`PERMANENT_SESSION_LIFETIME`.

Fixed
- The `undefine()` function did not always find the interview
answers.

Added
- Support for noun pluralizing and verb conjugation in Spanish,
French, Italian, German, and Dutch.
- Additional methods for `DAOAuth` objects.
Changed
- The output of the `interview_menu()` function, the `/api/list`
endpoint, and the `/list?json=1` endpoint now include interview
metadata.
- The `undefine()` function now accepts multiple variables names.
Fixed
- `DAObject`s that are attributes of `DAList` items had their
`instanceName`s rewritten when the parent list was altered.
- When an object that was already defined was edited using `fields`
with `datatype: object` or `datatype: object_radio`, the default
value was not showing.
- The office add-in was not using the best method to determine the
full URL of the server.

Fixed
- Translation of metadata titles not compatible with `translations`.
- JavaScript evaluated in local context rather than global context.
- Language not set when e-mailing assembled document in the
background.
