Emacs rust-mode should have its own repository

[ramnes]

Since partial cloning does not exist with git, any user interested in using and/or contributing to rust-mode have the choice between clone the whole repository for 1% of it, or directly download the file (thanks to this GitHub feature).

So, in answer to #1490, I really think that rust-mode should have its own repository, with its own contributors, issues, PR, etc. It still could be a part of this repository as a submodule, but I can't see the point of handling it here.

More generally, I don't understand why projects that are not part of Rust source code are in this repository.
