Introduce a new configuration for unzipping things directly into the topology jar

This goes hand-in-hand with jruby-gradle/redstorm#12 and allows us to
incorporate things like storm-kafka early on in the load time of a topology
while still allowing most JRuby-originating jar dependencies to be packed "as
per usual." (See fast-rsa-engine and others which pack jar files inside gem
archives)

Fixes #25
