Publish New Version

[cramertj]

This is just a request for a new version of tempdir to be published with the updated version of rand (from #40).

Also, the changes since the last release were nice and does improve the code so I strongly support this request.

Sorry for taking so long to circle around to this! Yes I think a release is long overdue. It looks like we haven't changed the public API since 0.3.5 but have probably shifted the minimum Rust version forward. I would like to release as 0.3.6 if we can.

[otavio]

It seems fine for me as well.

I've published a new version of tempdir. See the sparse release notes.

The only major thing here is that we've definitely moved the minimum rustc version forward to 1.13. I think this is ok, because that release is over a year old and appears to be available in most package repositories.
