Remove embed_migrations! temporarily

Unfortunately it will be impossible to write this macro using the Macros
1.1 API. While this is an important feature that I want to keep, I more
importantly want to keep the main repository working on stable. It will
have to live as a separate crate, and possibly have an API change to
work around build scripts.
