Subscribe to a specific objects changes

[chengfred]

In init command:

Currently we send name property to indicate the bucket name, and this implicitly subscribes you to all of a buckets changes, name: "note" => send all changes in note bucket

Perhaps: name: "note.abcd" => send only changes for object abcd in note

Or, a separate field:

query: "abcd" => send only changes for object abcd ( bucket from name: "note" still )

Not sure if we want to support more complicated queries yet
