Bring jdub up-to-date with other branches

The master here diverged a while back. So I just redid everything:

* Set default pool connection timeout to 1 second (from 8 ms)
* Allow TransactionManager to be swapped out by client
* 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
* Fix `row.bigdecimal` to use Scala BigDecimal
* Add `row.uuid` and `row.datetime` convenience methods
