Open source acknowledgements

Picmal wouldn't exist without a lot of other people's open-source work. Here's what the app bundles, where to find each project's source, and which license it ships under.

Most of the source links below point straight at the upstream project. If one rots, email support@picmal.app and I'll send the source tarball directly — free, for at least three years after each release that includes the component.
