More fixes - fixed docker builds - fixed mentions regex test - fixed DATABASE_URL stuff - change schema path in diesel.toml Address review comments - add jsonb column back into activity table - remove authors field from cargo.toml - adjust LEMMY_DATABASE_URL env var usage - rename all occurences of LEMMY_DATABASE_URL to DATABASE_URL Decouple utils and db Split code into cargo workspaces Co-authored-by: Felix Ableitner <me@nutomic.com> Reviewed-on: https://yerbamate.dev/LemmyNet/lemmy/pulls/67
