Add cocoapod

[i386]

Would be fabulous to see this as a cocoapod so I don't need to include this manually into my project :)

Two bridges to cross:

1. I'm not yet ready to declare the API final, i.e. tag it as v2.0. We could potentially add it tagged as a beta though
2. I have no idea how to construct the pod spec for such a complex project as ConnectionKit

If you could take care of 2. that would be a fantastic start.

Still no support for cocoapods?
