make twitter-util provided.

[johnynek]

You can't use storehaus without twitter-util, because Future is in our public API. We should make it provided which will ease some of the ivy pains we have seen.

Users need to explicitly add twitter-util to their deps.

What does this involve? Is it as simple as adding "provided" configuration to "com.twitter" %% "util-core" % utilVersion ?

[johnynek]

Yes, just add the % "provided" to that line.
