Closes #113 Adding required Sonatype OSS properties to poms to allow for...

... release
'release' is a bad name for this profile. I am going to update the wiki with release procedures. I wanted the actual maven command to be as simple as

```mvn release:prepare -P<release_profile> && mvn release:perform -P<release_profile>``` 

I generally don't like building javadocs and source jars by default because they add latency to the build but I could go either way on that- I also want the build to be easy to use and somewhat self explanatory. These artifacts are required, however, for staging in Maven Central.
