Support multiline eval.

For that to work we wrap the code we get in :{ ... :} and pass that to ghci. If the code we got is a function binding we also wrap it in a let statement.

Should work at least on our codebase, haven't tried with anything bigger.

Before we merge this I'd like to add some tests and hear from others that it works for them (hopefully on slightly more complex projects).

Hey, I'm in the process of traveling across the world and heading back home. I'll be fairly unavailable (no laptop) for the next 3 weeks. Feel free to merge if you're comfortable with it. Sorry I can't be more helpful right now!

I'll try to look at this today, though.

Thanks for the heads up. I've not worked on this since I opened the pull request. I still plan to add some tests before merging this, though.

Do you have any preference for a Haskell testing library?

I like hspec with quickcheck, but don't care that much. Whatever you
think is best.

Ok, I think I won't get around to test this in the near future, so I'll just trust Haskell's "if it compiles, it will probably run well" magic fairy dust, the fact that travis compiles it fine and that it works locally.

@everyone: If you want to write tests, please do, I'd be happy to help you do that!
