v0.3.0

Added

• Project webhooks: a webhook's projects: (all, or names) hears the projects' own events and those of every application reading from them, including applications added later, combined with applications:; three project events, commit_pulled (the commits a pull brought, newest first with author and subject, whether history was rewritten, and the applications whose folders changed), pull_failed and pull_recovered, each sent once per change of state; application messages and the send history now name the project, and GET /api/v1/webhooks adds all_projects, projects and project_applications (see docs/webhooks.md).
• The web UI from unified-ui 0.4.0: project webhooks on the Webhooks pages, and the Webhooks card always on the Overview.
