v0.6.0

Webhooks name each issue's labels. Updating a self-hosted copy needs no migration and no new
setting.

Added

• Webhooks: each issue in an issue, comment or proposal event carries labels, a list of
  { id, name } in the order of labelIds, with the names as of the event. A receiver can act on
  a label by its name instead of looking up its id. labelIds is unchanged. (#56)
