Updated to rust nightly 2015-03-04

[Victor-Savu]

I updated cargo to build with the 2015-03-04 rust nightly build. There seems to be some problem with benchmarking in that version, so [bench] tests failed. Otherwise, there seem to be no regressions.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @wycats (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Hm it does indeed look like there are some more bugs to be fixed here. I think we'll need to fix the arithmetic overflows in rust master before we can land this PR. It also looks like there are some plugin changes?

If you update docopt to the most recent version as well I think this PR can also knock out #1377!

I thought docopt was at the mos recent version when I first wrote the code (24 h ago). I set every dependency to "*" and did a clean build (I also deleted ~/.cargo). I then reverted to concrete version numbers.

I can have a look in about 12 h or so after I come back from work. Cheers!
