[WEB] Derby Mentors, please 'svn update' to make web changes visible

Changes include:

- derby_comm.xml now links to Jira and to the jars on the downloads page.
- Added a new papers/misc.{xml,html} page for integration topics taken from the 
mail lists.
- Updated site.xml and papers/index.xml to link to misc.html.
- Updated faq.xml to include info on releases and Jira.

So if a mentor will 'svn update' to make the web site changes visible,
I'd appreciate it.

regards,

 -jean
