Removed Riak dependencies.
Refactoring for Maven build, removing Ant build.
Moved (actually copied for now) dependencies for Morphia, Johm, and Voldemort that are not in the Maven repo.  Will need to include them in the output artifacts.
Removed dependency on local morphia jar, utilizing a snapshot at https://oss.sonatype.org/content/repositories/snapshots/com/strategicgains/morphia/morphia/ instead.
