Navigate to use when clicking anywhere in a use report line

The code for the use report is incredibly ugly and really needs
to be cleaned up. We could probably get away with generating a
single HTML report and use that for all matches, instead of
generating one widget (with two labels) per use, each with its
own HTML inside...

Doing it all in one document would also allow us to easily implement
a select + copy action.
