realized I was inheriting nipkgs in my nixosSystems

added ways to use different branches of nixpkgs
made unfree packages have to specified
switched to nix master branch
moved sxhkd from a seperate flake
switched spotify and maim versions because both are broken on nixos-unstable right now
moved afk-cmds from local to remote
added flake-utils for easier devShell decleration
switched my mom's laptop to stable branch

modules/unfree.nix
