accept card defs for type+discussion

When this is done, fix http://en.dwagn.org/wagn/*watching+*right+*structure (and migrate)

---

This WQL was there:

 

{"or":

{"and": {"right_plus": ["*watcher", {"refer_to": "_self"} ], "not": {"type": "Cardtype"} } },

{"type": {"right_plus": ["*watcher", {"refer_to": "_self"} ], "type": "Cardtype"} }

}

 

But that's not correct. We'll have to fix it at some point, but I'd rather not just copy it everywhere in a comment.

---

It now has valid/working WQL. no migration yet.

---

we're doing a significant reworking of the following (watching) behavior soon. the WQL mentioned above will be addressed there.
