Hazelcast and Blueprints dependency version bump, fixes maven build.

Just a very small thing. The maven build has been broken due to referencing outdated dependency versions. This bumps the following dependency versions, thereby fixing the maven build:

hazelcast: 3.0-SNAPSHOT -> 3.0.1-SNAPSHOT
blueprints: 2.4.0-SNAPSHOT -> 2.5.0-SNAPSHOT

It doesn't do anything else. I'm not sure it warrants a pull request, but I didn't find a way to attach a simple patch.

Keep up the great work!
