MacOS support

[Kataiser]

I don't own a Mac, but I'd like this project to work on MacOS anyway.

I'll give it a go
Shouldn't be too hard considering python is Crossplatform

[Jan200101]

In theory I just need to modify processes.py to get proper Mac (and Linux) support
but there are too many things that are done poorly in my opinion so I'll take care of those too

[Jan200101]

alright this is gonna take WAY longer
the entire codebase is a mess and not optimized for crossplatform usage
not to mention the dependency on windows executables

[Kataiser]

Yeah, the code (especially main.py) is a mess due to me not really expecting this project to grow much, and then not refactoring enough. Thanks for at least giving it an attempt, though!

got it to work on a crossplatform base (like mentioned in the Linux issue)
the only thing missing right now is the names of the processes
