1.14 release notes: A bit more hierarchical organization near end of document
* docs/release-notes/1.14.html (support): New h2 section "Support and Release Planning." (lts-release, svn-1.10-old-stable, svn-1.9-deprecation): Demote from h2 to h3 within #support. (enthusiastic-contributors): The above change makes the final "Enthusiastic Contributors Welcome!" section stand out a bit more. Mention finishing the Shelving and Checkpointing features among the things that people could contribute to.
