Notes: Inconsistencies, usability issues

[joshuasbates]

The Notes component has the following inconsistencies with the current implementation demonstrated in APM using saffron:

• The component should be rendered in a BlockPanel.
• When editing a note, the edit control should appear inside the note's `CardBody'. Currently, the entire note card, including the card header, is replaced by the edit view.
• There is no support for rending the "add" control, which should be rendered inside the block panel (at the top).
• Various shortcomings of EditableNote:
  • The note data is not provided in the callbacks, so consumers can not track which note is being edited.
  • The edit view should support a "saving" mode for the note so that the button text can reflect the state, and buttons/inputs can be disabled while database actions are in progress.

I have already prototyped and tested changed in the Workflow management components, and will contribute those changes back to react-gears (and update the documentation) in the near future.
