1.6/1.6.1-SNAPSHOT not recursing/reporting all packages

The introduction of the maven.jdepend.components property causes a backwards compatibility problem. Our JDepend reports stop reporting on all packages with 1.6 and 1.6.1-SNAPSHOT; 1.5.1 works great.

1.6 introduces it and defaults to pom.project. To have the same behavior as 1.5.1 in 1.6 and 1.6.1-SNAPSHOT, the components property must be empty.

With the changes made by MPJDEPEND-7, the components property can be set to nothing (1.6 would crash if set to nothing).

I think the best answer is to default maven.jdepend.components to nothing, so upgrades are transparent (instead of having to set the property to nothing to get it to work - and other users spending a bunch of time as I did!) and more aligns with JDepend's components setting is optional.
