Whoops, didn't prefix FSRef<->NSURL categories.
Replace FSRefReadData/WriteData, blockSize.

 - Removes use of BufferUtils FSRefReadData, FSRefWriteData functions.
 - Remove NotationController and NoteObjects blockSize getters.
 - Partially modernize/NSError-ify:
    * -[NotationController readAndInitializeSerializedNotes:]
    * -[NoteObject exportToDirectoryRef:withFileName:usingFormat:overwrite:]
Transition remaining NoteObject static setters.
Replace CFUUIDRef/CFUUIDBytes with NSUUID, full-stop.
Add future NVCatalogEntry class.
