[jboss-as7-dev] depending on jackson-mapper-asl

[Emmanuel Bernard]

I agree with Andy but having different release cycles we should isolate AS 7's libs from the rest anyways.

For this problem, I think we should:
 - bump up AS 7 Jackson version to the one used by Avro
 - isolate this library for future proofing

While we can do some really cool things now through modules to have different versions of the same components floating around, I fear that we will get lazy, and before you know it we end up with dozens of versions of similar or the same components floating around, and that will become a support nightmare.
