Not supporting Django 3.0.x

[moojen]

The forms.py still uses some "old" code from Django 2.x, which has been deprecated in 3.0.

I got the following errors and have added my solution to them, which made the app work (but not thoroughly tested).

• from django.contrib.staticfiles.templatetags.staticfiles import static

• ModuleNotFoundError: No module named 'django.contrib.staticfiles.templatetags'
  Solution: replace first line with from django.templatetags.static import static (and add an if statement based on the Django version)

• from django.utils.lru_cache import lru_cache

• ModuleNotFoundError: No module named 'django.utils.lru_cache'
  Solution: replace first line with from functools import lru_cache (and add an if statement based on the Django version)

Hope this helps anyone!

In addition to the above, in the second line it still mentions:
load staticfiles which should be load static as of 3.0 as staticfiles is removed
