I have such a PG and it seems there are always some ports that don't show up in `port outdated` after I bump the version (presumably because PortIndex can fail to detect that a port imports certain PGs).

My initial thought was that it would need support in base and that a port's revision would be the sum of its base revision and the revision of all of its PortGroups.  Unfortunately, that would get ugly if a portgroup were removed.  It would also be confusing to determine exactly what revision was being used in a bug report.

My next thought was that we could add another version field for PortGroup revision.  We could use the highest value set amongst all the port's groups when comparing versions.  That still has the downside of causing problems if a PortGroup is removed.  I suspect many such cases would come with a revbump anyways, so that's probably not too big of a concern.
