#minor: Make Jackson Plugin unique in order to support Java9 modules (#110)

BREAKING!

Manual update to "snapshot.properites" required

Before
```
serializer.json=au.com.origin.snapshots.serializers.JacksonSnapshotSerializer
serializer.orderedJson=au.com.origin.snapshots.serializers.DeterministicJacksonSnapshotSerializer
```

After
```
serializer.json=au.com.origin.snapshots.jackson.serializers.JacksonSnapshotSerializer
serializer.orderedJson=au.com.origin.snapshots.jackson.serializers.DeterministicJacksonSnapshotSerializer
```

You will also need to manually update any imports in java code if you have used them
