Name of detour crate changed

[Hpmason]

Hi, I'm the maintainer of the detour fork!

I just renamed the repo/crate, so it's going to break your project, I'm really sorry about that.
But it's now on crates.io now here, so you can add it to your Cargo.toml!

retour = "0.1.0"

Figured I send out issues to the repos using it to avoid any confusion/frustration. Again, sorry about that, but this makes things a lot easier going forward.

Happy hacking! 😄
