Small change to artifact version parsing.

We currently many projects that use an OSGi compatible scheme for release version numbers. The OSGi spec does not currently allow a "-" to determine the location of the qualifier. So instead of the maven standard like this:

1.0.1-beta-1

We have something like this:

1.0.1.beta1

Maven's currently handles this by treating the entire version string as a classifier. It would be helpful this could be parsed as
major = 1
minor = 0
incremental = 1
qualifier = beta1
