v0.7.2 — Automatic migrations & navigation polish

What's new in 0.7.2

• Database migrations now run automatically when the app starts — there's no separate migration step, and editing or removing the Compose command can no longer skip them
• Fresh installs and existing databases both come up cleanly on SQLite and PostgreSQL; a database that was once started without migrations is detected and adopted safely, without changing any data
• Deleting a model now returns you to the folder you were browsing instead of jumping back to All Models
• The PrintStash logo now takes you back to the collection you were in, rather than always to All Models
