Ref T10747.
- Adds a "Use Results..." dropdown to query result pages, with actions you can take with search results (today: create export; in future: bulk edit, export as excel, make dashboard panel, etc).
- Allows you to create an export against a query key.
- I'm just using a text edit field for this for now.
- Fleshes out export modes. I plan to support: public (as though you were logged out), privileged (as though you were logged in) and availability (event times, but not details).
This does not actually export stuff yet.
