Small fixes

Just sending a request with the fixes I found were needed to get everything working. (Under Jetty 9.1.5 and JDK7 in my case)

- bump icu4j version up, as the one referenced previously had an issue with one of the classes, per: http://stackoverflow.com/questions/15701319/how-to-solve-unable-to-process-jar-entry and http://jira.codehaus.org/browse/JETTY-1201

- Add full set of Jersey dependencies to middletier build, as there were missing classes relating to OSGI that prevented application startup

- For some reason the edge web.xml was declaring it was serving turbine services, which caused the launch to fail. Those have been removed. (Hystrix streams have been left in, and these are confirmed to work through a remote Turbine aggregator)

- The cassandra store sources were missing the annotation depenendancies. Those were added.

- And I just noticed this also has the switch from Dynamo to Cassandra included... this can of course be reverted per whatever you'd like the default to be.

Hope this is useful to others.
