Adding Desolation of Smaug and Battle of the Five Armies

[Annatar]

Hi everybody,

It looks like nobody's working on adding the contents from DoS and BotFA, so I started it myself. I also did some minor cleanup, like typos and such.

Is anybody else working on that, or can I take it over for the time being?

Also, is somebody here willing to beta-test the new data files? I'm aware of a few things that aren't working, but I also need somebody to proof-read everything.
