Upgrade dependencies so it compiles out of the box

To show my total disdain for the bison project, I tried to compile it, just to see live how terrible it is. I was distraught by the complicated build instructions though: I was not going to get my computer polluted with custom, old versions of scalaz-streams, so I moved the version forward and changed the code that refused to compile. As a bonus feature, we also grab the latest scribe.

There are some failing tests, but that seemed to be by design, so I kept them broken. I found one of the working ones way too boring though, so I changed it. Now it has Lannisters in it. Everything is better with Lannisters,
