Resolve javadoc

I ended up resolving most of my earlier concerns and only have a couple changes that need to be done the the FTL template. Most importantly, I corrected the deprecation warnings through the Impl files. This pull request includes the Javadoc updates using *-Dupdate=true*, *ant javadoc* warning fixes, and *ant javadoc-all* warning fixes.

I have not built the services and I've contacted Jonathan Lee for fixing some params in SO files that I was unfamiliar with. He notified me that his work on these should be finished (hopefully) by tomorrow or Thursday. I will attach the generated file issues/warnings in the ticket that we may need to look at before the 6.2 release.
