Add text/rust for Rust source code

The attached patch adds a text/rust type (and test file) for Rust source code.

The Rust programming language announced version 1.0 on May 15th and is now considered stable. Announcement: http://blog.rust-lang.org/2015/05/15/Rust-1.0.html

Identification is by glob pattern *.rs. This file extension is explicitly documented in the Rust reference, quote:

"Source files have the extension .rs."
(Source: https://doc.rust-lang.org/reference.html#crates-and-source-files)

The test file is is a simple Hello World program (source: http://doc.rust-lang.org/stable/book/hello-world.html).


Concrete use case: In KDE's IDE application KDevelop, language support plugins specify the source code documents they support via MIME type lists. Having shared-mime-info provide this type makes this much easier. Further, Rust itself is a major open source project that would benefit from this integration.
