fixing (by removing) note_Data reference, and replacing it with a TODO
adding Files to local/remote sync trackers, AND moving remote tracker setup into turtl.js instead of the Sync model. this gives us one place to setup local/remote trackers (obviously, removed the correspding function from the sync model)
removing code that removes board keychain entries on board destroy. no longer needed since the API removes the entries for us (and the removal will just sync to the client)
converting File model/collection for syncing (untested)
adding Files to profile relations.
