Extend Decodeable to j.u.ArrayList

NOTE: I have submitted the Eclipse CLA

I've been bitten by this discrepancy a few times recently, especially when passing data between clojure verticles. I think there's precedent - clojure.data.json preserves ILookup semantics in round-tripped data.

Thoughts?

@johnchapin - thanks for the fix! Is there a reason we have to use ArrayList here? Would extending Decodeable to the more general List also work?

[johnchapin]

Good call - List would be better and lines up with the list of extended classes for Encodeable. I've updated the PR.

Looks good, thanks @johnchapin!
