Update jlhose.go

More fields and fixed bug with empty left outer joins
Update jlhose.go

Yucky, but does the job of allowing either all articles or articles from a specified newspaper to be streamed. Very useful for testing SFM!

New URL scheme:

curl -s localhost:9999/ -H "Last-Event-ID: 9870000"

streams everything

curl -s localhost:9999/guardian/ -H "Last-Event-ID: 9870000"

streams guardian articles

Using a pubsub at the database level would definitely have made this simpler...
