Finch.io 0.2.0

This release is a result of a huge project redesign: instead of mono-project, it's multi-project now. We've managed to resolve the plugabble JSON libraries ticket. So, there are two new JSON modules in Finch.io: finch-json (own immutable JSON) and finch-jawn (bindings to Jawn library). Finally, Finch.io is on Maven Central now:

"com.github.finagle" %% "finch-module" % "0.2.0"
