0.8.1 Oct 6, 2016: Fixed pom.xml bug

Soon after we released 0.8.0, we discovered that the shaded jar was misnamed as sketches-core.0.8.0-with-shaded-core.jar instead of sketches-core.0.8.0-with-shaded-memory.jar. And internally both the core libraries and the memory package were both shaded, which was not the intent. Only the memory package should have been shaded. This is fixed with this release.

The impact of the bug was relatively low as it would only be detected if you installed the shaded jar and tried to reference the core sketches. All the other jars are fine.
