Add option to disable abort notification

[j4k0xb]

Closes #3287

It's my first PR here so not too familiar with the codebase, hope the way of excluding the logger target is how it's intended to be used (still logs to files/stderr).
I ran clang-format and tested it on Linux.

I think it should be Enabled by default, at least for the next few versions, and then we can ask the community how they feel about it. This way the backlash would be minimal.

I'm not a maintainer, but I am a programmer and this looks great to me. I read the code changes and they make sense. The logging is preserved and only the notification is toggled by this option.

Is there any reason not to merge this at this point? It makes the software better and from my review of the code, I don't see how it could introduce any regressions.

@j4k0xb thanks for implementation, and @AlexFolland thank for reviewing the code. I'm a maintainer but I mostly do triage. We should wait for other devs to review and merge this. I typically only merge documentation or minor code changes, and this PR contains 33 lines of code across 6 files.

@j4k0xb and @AlexFolland it would be a great help if you can give us your opinion on other PRs. The more eyes we have on the codebase, the safer the users will be and the better code quality we would have. I appreciate every bit of help.

Thank you again for the PR and for the review.

I'm not deeply familiar with the code base, but even I can tell that this particular PR is just a bunch of settings-related boilerplate and documentation, plus the one change that actually interprets and uses the setting's value. It's a very simple change, so that's why I could easily claim to have reviewed it.

Please review and merge this soon. It looks ready and the abort notification is disruptive to regular screenshot workflows, especially when capturing particular moments while gaming. I would prefer to never see an abort notification in my next attempt at the right screenshot after starting a capture at the wrong moment.
