updating akka dependency to 2.3.2

[lamdor]

I'm not fully sure if akka 2.2 and akka 2.3 are fully binary compatible nor if chill-akka would have any problems with it. But we are on our way to upgrading to akka 2.3 and as this is one of our major dependencies (thanks), I wanted to make sure that it was okay too. And it was. So here you go.

Thanks for taking the time to do this.

So, we tend to keep the lowest dependency that is compatible with the most recent version. In this case, I think you are okay using this and letting sbt evict our dep in favor of yours. So I would tend to think we should not merge as is.

What I would merge is that akka should be a % provided dependency, since clearly you need to have your code depend on akka to use chill-akka. Would you be willing to make that minor change for us?

[lamdor]

Agreed. I've made the change. Thanks.

Great! Thanks.
