Bring jdub up-to-date with other branches

The master here diverged a while back. So I just redid everything:

* logula / DW logging -> grizzled
* Update to Scala 2.9.2
* Bump other dependencies
* None works correctly
* Joda types work correctly
* BigInt / BigDecimal work correctly
* Travis CI support
* Maven Central deploy support
* Add Simple copyright
