refactor: Backend dependencies and more

- Add backend dependencies: One backend can now depend on another
  backend.
- Re-factor 'DownloadArtifact':
  - Rename 'DownloadArtifact' to 'DownloadConfig'
  - Remove attributes 'name' and 'version' not relevant for downloads
  - Add helper properties:
      - 'filename' parses the URL to extract the file name from the end
      - 'headers' calls the function to generate a HTML header for the
         download
- Add OutputLogger helper class
- Re-factor handling of backend configurations in the target profiles.
