Setttings: strip whitespace between entries

[fliiiix]

It took me a lot of time to figure out why this config does not do what I would expect:

CSRF_TRUSTED_ORIGINS = "https://foo.bar.example/, http://foo.example/"

The first commit 6400003 addresses this and strips white space.
I feel like refactoring that out into helper functions a4e34ac makes it more readable, but i can also remove that commit if thats not in line with the project.
And i used black for formatting 03c10bc since i wasn't sure what the policy is here, but also in a extra commit which can be removed easily again.

I feel all these changes are useful but let me know :D

Hi, thank you for the PR, I am very busy atm but will try to look into this as soon as possible.

ok so sorry for the long delay. The logic change looks good. May I ask you to do two things:

1. revert the formatting, It was well intended but formatting is a very difficult topic that has not yet been 100% decided
2. can you change the branch to merge into feature/vue3, because I don't want to make any setting changes on develop any more

thank you

I can highly recommend using black and stop discussing about it, worked well for me at work and in my open source projects,
but i removed it from this MR

can you change the branch to merge into feature/vue3
rebased on new branch

let me know if there is anything else required to get it merged :)

thank you. I know black works very well but my personal preference is in the way, I just simply dont like how it looks.
