* Shutdown:
- Clear more resources in peer manager, netdb, stat manager,
session key manager, naming service, tunnel dispatcher,
OCMOSJ (result of testing with jvisualvm)
- Don't call wrapper on shutdown (starting two threads) if we
were started with runplain
- Fix problems where a requested unsigned update would actually
kick off a signed update
- Fix problem when policy set to notify, and clicking
check for update, incorrectly causing unsigned update download
and bad messages
- Verify zip integrity of unsigned updates
- Move zip files to router dir, not base dir
- More tweaks and cleanup
- Add new unsigned update option, triggered by
last-modified date, using the new EepHead.
Buttons still are not hidden after download complete.
- Make the .sud updater use the temp dir when proxied
- Several cleanups
