Support runtime directory

[utkarshgupta137]

XDG_RUNTIME_DIR is a part of the XDG Base Directory Specification.
I want to incorporate this crate in a couple of tools which require runtime_dir.

Should we support the permission check for the directory, as mentioned in the specification? You can check the changes here: https://github.com/utkarshgupta137/etcetera/tree/runtime_dir_check.
Personally, I'm not a fan since we're returning Option, not a Result.

Hi, sorry for leaving this awhile, but how would you feel about maintaining this crate? I don’t feel strongly about this project anymore and you clearly have far more interest than I do, so I’d be more than happy to transfer crate ownership to someone who cares :)

Yeah, definitely. I plan to use this crate to replace the dirs/dirs-next crate, so I would be happy to maintain it. You can transfer the repo to me. Not sure what is the process for crates.io.

I’ve invited you as a collaborator on GitHub and an owner on crates.io!

Thanks, I've accepted both! I've raised another PR with minor doc changes & version bump.

FYI, the xdg crate checks the runtime directory as per the spec: https://github.com/whitequark/rust-xdg/blob/v2.4.1/src/lib.rs#L301

I suppose a breaking change wouldn’t matter much since this isn’t a popular library, which isn’t at 1.0 anyway. How pedantic you want to be about following the spec is completely up to you!
