Update for 2.10, prepare for push to Sonatype RSS repo

Greetings, I updated your seemingly very capable project to Scala 2.10.  In addition, I added support for publishing on Sonatype OSS.  The ticket for that is at https://issues.sonatype.org/browse/OSSRH-9239.  If you can create an account on that site, I can add you to the repository owners (and remove myself if it bothers you to have someone else with publishing access).  

Note that the project requires https://github.com/topping/naggati2.  I've posted a pull request for it at https://github.com/twitter/naggati2/pull/10.  

Also note that Sonatype is allergic to having ```<repository>``` elements in POMs that are published there.  We'll have to put a few more changes in here to get things up to snuff before we can release.

Thanks for your consideration of this pull request! Please do not hesitate to request any changes that you would like to see.

Brian
