Unhandled exceptions causing Ruby aborts about capnp-ruby

[cstrahan]

@ntalbott Hey, thanks for your interest in the library. Unfortunately, I've been incredibly swamped and haven't had a chance to complete things; as a work-in-progress, it's still very much broken.

I'll hopefully have some more time within the next couple weeks to bang out a first stable version. Feel free to drop back in and pester me to get it done :).

@cstrahan Pester pester! I'm not quite adept with C extensions, but I'm working on improving the ruby objects to make them a bit more user-friendly.

I'm so glad you went with wrapping the C++ library. I really want to use this library to demonstrate capnproto to my team (mostly all rubyists), and implement some fun tools for us to build things with.

@Spaceghost Thanks :). I'll set aside some time this weekend to work on this.
