Merge branch 'rs-system-note' into 'master' 

Add SystemNoteService class

The Note model was basically two models crammed together - one handling user-created notes
(i.e., comments on things) and one handling system-created notes (i.e., references).
This splits out the system-specific stuff to a new SystemNoteService class.
