Merge #391

391: Change missing_docs from deny to warn. r=eldruin a=Dirbaio

It is annoying to get hard errors while developing, it prevents testing things out
without documenting them because it fails the build.

This changes it to warn, which has the same effect in CI (because it already has `RUSTFLAGS: '--deny warnings'`),
but still allows buildilng.
