3.1 Upgrade Processing Part 3 of 3

.. PM chart is deprecated, so when loading an LTM chart
   with skiba curves is implemented instead.

.. we cannot easily add charts to the layout without refactoring
   HomeWindow so have moved that out of scope

NOTE: The upgrade processing has not been activated -- but can
      be once we build and issue our first 3.1 RC.
