Fix build #3 by correct errors found by awesomebot

We shouldn't normally need to do this with future pull requests, now that we've enabled on travis.

I would also make the suggestion that all maintainers should start using PR rather than editing the file directly so we can all utilise awesomebot validation via travis.

Regarding the 404s from crates.io i've opened rust-lang/crates.io#788

I think PRs are not strictly necessary for Travis. The commit which triggered https://travis-ci.org/rust-unofficial/awesome-rust/builds/244830080 was not done via a PR.

I guess in the future we'll see more deprecated/moved URLs etc. long after the change was made. I don't suspect many new PRs to have issues regarding URLs.
