Fix ability to set EDAMNote "attributes.xxxx" properties (key path). Sane names for date category methods.
Expose more information for better bridging to EDAM:
- ENSession now allows you to request an appropriate note store client from an ENNoteRef or an ENNotebook.
- ENNoteRef and ENNotebook both expose a readonly "guid" property so you can find them with the EDAM API.
- findNotes.. adds an updateSequenceNum property in its result object.
(all via the advanced header).
