Docassemble

Fixed
- Bug with `ip address ban enabled`.

Added
- The `noun_is_singular` keyword parameter to the `noun_plural()`
function.

Changed
- The `date_difference()` function's `describe()` method will now
describe times.
- In error messages from YAML parsing, fall back to displaying YAML
with `repr()` if displaying the YAML as YAML fails.

Fixed
- Bug with `ip address ban enabled`.
- Bug with displaying interview logic history.

Fixed
- Problems with comboboxes and `disable others`.
- Problem with TIFF to PDF conversion not using compression.
- Problem with `show if` when comparing a `variable` to the empty
string.
- An empty `js show if` caused the field not to be shown, instead of
being ignored.

Changed
- `DAWeb` no longer requires the `data` parameter to be a dictionary;
it will pass the `data` parameter directly to `requests`.
- Upgraded `redis`, `celery`, `aiohttp`, and `Pillow`.

Fixed
- Issue with one of the fixes in 1.4.97.

Added
- The `pdftk` option under `attachment` and `features` for filling in
`pdf template file` attachments using pdftk instead of pikepdf.
Changed
- During the Docker image build process, `pandoc` will run once, so
that the first user to assemble a document with `pandoc` will not
experience slowness due to LaTeX needing to generate files.
- Appearance streams will be generated when using `pdf template file`.
- Error messages related to problems in the source code will no longer
be displayed to the user unless the user is an administrator or
developer. If you want these error messages to appear to all users,
set `debug: True` and `development site is protected: True` in the
Configuration. The error messages will be available in
`docassemble.log`.
