bump to 0.3.1 and work around cargo publish issue (#992)

* bump crate versions to 0.3.1

* workaround for cargo dev-dependencies problem

To work around a known issue with `cargo publish` ([1]), update all
self-dependencies under dev-dependencies to use `path = "."` instead of
a versioned crate, as `publish` insists on fetching from crates.io,
despite a correctly versioned crate being available locally.
