[VOTE] Change ServiceMix version to 3.0-SNAPSHOT

[Guillaume Nodet]

As we have to change the package names to org.apache.servicemix, i 
propose that we change
the version number of ServiceMix to 3.0 to reflect this, and also the 
fact that we are focusing
on full jbi compliance for both the container and components.
[ ] +1 Change version to 3.0-SNAPSHOT
[ ] -1 Keep 2.1 version number (provide specific comments)

Cheers,
Guillaume Nodet
