Django 4.0 Support

[martin-schlossarek]

Seems like django-mass-edit does not work with Django 4.0:

$ python manage.py --help
Traceback (most recent call last):

ImportError: cannot import name 'ugettext_lazy' from 'django.utils.translation' (/home/somehome/.local/share/virtualenvs/someproject-kDcDKEru/lib/python3.10/site-packages/django/utils/translation/__init__.py)

The mentioned ugettext_lazy method was deprecated since Django 3.0 and is now finally removed from Django 4.0:

@martin-schlossarek I have committed fix in master branch. Could you please verify, it works for you?

[tiagocordeiro]

@PetrDlouhy I just tested it locally and it works fine with django 4. When do you want to publish an update on pypi?

Thanks!

[PetrDlouhy]

Unfortunately I don't have access to do that. @bufke Could you please make a new release? I did make all the tests working so it should be easy.

@danialmalik Maybe we could wait for your MR #96, if you finish it soon.

Hi @PetrDlouhy,

Sorry for the delay, I have been stuck in some stuff. I'll probably finalize the fix PR some time today.

[PetrDlouhy]

@danialmalik No problem thank you very much that you managed it.

@bufke I prepared everything for the release 3.4.1, so you would just have to upload it to PyPI.

[bufke]

Can do, I'm going to update the compose file, as I like testing that way. I see you uploaded a github actions file. Should I remove the older .travis.yml? It's targeting mostly obsolete versions of python/django.

[bufke]

Done https://pypi.org/project/django-mass-edit/3.4.1/

[PetrDlouhy]

@bufke I deleted the .travis.yml, it was obsolete and merged your MR. Thank you for the release.
