Remove extra searchable fields from fbopen
fbopen: test sorting by relevance

Want some tests before refactoring
Fist stab at simplified setup method. To be rebased...
Second stab. fbopen works. canada and uk fails.
Canada uses new setup query method
ukleads uses new setup query method
italocations uses new setup query method
Remove dead code :-)
extract method
Initialize queries with empty options by default
Add accessor to query_fields class variable

That should make it read a tiny bit better
No need to explicitly pass args to super here.
