Added example specs to make sure they work, and even found a bug while doing that. Because
sbt wants to decide whether to do things sequentially or in parallel, so we need to register
Play.stop() to be executed when the Status completes, not in a finally clause. Fleshed out Scaladoc
primarily of OneAppPerSuite.
Apparently forgot to check in the files that got some fleshing out of Scaladoc, which
I described in my previous commit message.
