Attention, release managers and release note smiths

[Rick Hillegas]

I have clipped a patch to DERBY-2570. This is the first rev of a tool 
for generating the release notes from some JIRA reports and a 
templatized release description. I'm hoping this will be useful for 
building the 10.3 release notes. It would be great to get feedback 
soon--I'm going on vacation next week and there won't be a lot of time 
to sand this down after I get back.

Thanks,
-Rick
