v0.4.0 — the no-dash label rule

Published as @moshcoder/moshpit-name@0.4.0.

Publishes the letters-and-digits-only rule for labels and endings — no dashes in a Moshpit name.

The rule had been correct in git for a while but was not reachable from npm: the caret range ^0.3.x cannot resolve 0.4.0, so dependents kept validating names against the old rule. This release is what makes the published validator agree with the repo.
