Convert artifacts to registry hunter

[scudette]

This is an overarching issue to manage converting the artifacts to the registry hunter. We currently have a lot of specific artifacts to search for certain things in the registry. But the registry hunter is a larger automated artifact that will replace all those individual artifacts.

The registry hunter is more useful as we can just collect it all at once using a single artifact, it handles ntuser and raw registry transparently and has better searching.

In the first instance we need to mark those artifacts as deprecated - possibly in the GUI and refer users to the registry hunter.

This issue will also cover the artifact exchange artifacts which will also be converted as needed.
