Improve the setup and reduce warnings

- Use repositories with more recent content for the targlets so that one
can work at development time with newer dependencies as soon as they are
available to catch problems earlier.
- Add project encoding for the astro example.
- Eliminate warning about missing org.eclipse.wildwebdeveloper.markdown
keyword id.
