Merge branch 'release/v0.4.2'

* release/v0.4.2: (31 commits)
  Bump version to 0.4.2
  Archive Cargo.lock
  Absolute path to cargo2junit
  Install cargo2junit in test build
  whoops
  Ah yes, why bother with correct documentation anyway?
  Move rustup/cargo install to only the jobs that need them
  Allow rustfmt failure until we fix capnp gen being fmt'ed
  ...
  okay I guess?
  rustup
  actually we don't need clippy for non-MR things
  okay gitlab, be that way
  and use stable goddamit
  okay make builds work better for merges
  Actually, only build if linting checks out. And make Gitlab CI work.
  Try to get the Gitlab CI to cooperate.
  Build test harnish as part of the `build` step
  Make docker containers only be built when necessary
  Correct gitlab-ci.yml
  ...
