Build fails with rustc 1.4.0 nightly

[milgner]

After the stable branch complained about the use of #![feature(plugin)], I built myself Rust 1.4.0 nightly. But I can't get shiny to work. Unfortunately I'm a total Rust noob, too (just want to write nice tests from the start), so it may be that I'm doing something elementary wrong.
Nonetheless, here's the output:

[ujh]

I've opened #7 with a fix. But I'm not 100% sure that it still works. I just made it compile again.
