[Release Automation]  Updated DraftReleaseNotesTask so that it has a simpler (and less error-prone) way of finding the location of the jar files and uploading them to the release notes.  It's not uploading source files though so the next step is to find out when that stopped working.
[Release Automation] Chaining the tasks into one complete release process.  Missing the dependency on the Nexus upload at the moment, which is only a tiny bit important.
