Update config for publishing to Maven Central:

- Add fake Javadoc files with readme.txt referring to docs.zip file
- New staging URL (it also requires to send a "close" command at end, not yet implemented)
- Snapshots not working yet, it fails to upload maven-metadata.xml because server sends error 400
