Update rubocop

[bastelfreak]

• remove trailing whitespace

Enabled:

• Style/HashSyntax
• Style/DefWithParentheses

hey. Do we want to keep enabled cops in the .rubocop.yml or should I remove them?

[bastelfreak]

@dj-wasabi what do you think so far, are there any cops that you would like to keep disabled? I think there are ~25 left which I will deal with tomorrow.

I did one commit per cop, which makes reverting them easier if any of them introduces a regression.

Hi @bastelfreak

This looks very very good. If you could fix the conflicts I'll be very happy to merge this request. :-) 👍

[bastelfreak]

Rubocop doesn't always find all issues related to one cop. It found a few old issues after the rebase. will fix that in a few.

[bastelfreak]

I'm ready for merge if this turns green.

Many thanks!
