Scala 2.10 support

Hello, @bruntonspall @bmjames @jennysivapalan.  Please could one of you take a look at this for me.

Think it should be fairly straightforward.   I removed 2.9.0-1 support from the build.sbt, as @bruntonspall had already broken it's support by moving to lift-json 2.5M4.

Thanks,

Phil
