itchanged.org firefox plugin - parser doesn't pick up "item-license"?

I _think_ the parser (in Microformat.jsm) is wrong wrt to the "item-license" element. It's defined as:

```
"license" : {
  datatype: "microformat",
  microformat: "rel-license"
},
```

It seems to look for "license" class instead of "item-license", and i can't find any other mention of "rel-license" in the code...
