fritzing: 0.9.3b -> 0.9.4

Notes:

* fritzing still needs an older version of libgit2
* releases no longer directly correspond to tags in the git repository, they are
  using build numbers instead
* the fritzing-parts repository is no longer versioned at all, the master branch
  contains the latest stable release
* a `parts.db` file needs to be generated from the fritzing-parts files during
  the build

(cherry picked from commit 0f6b8b7)
Otherwise it wouldn't build.  Master PR: #98381.
