[Axis 2] UUID Generator for Axis 2

[Saminda Abeyruwan]

Hi all,

When Axis2 uses sync/async message transfer via duel channel, current 
code uses System.currentTimeMillis() to set message id.

A UUID generator can be found in Commons-id, in Sandbox. But they 
haven't done a release yet.

Is it possible to integrate this facility with Axis2 to genertate 
message id with Commons-id UUID support.
