Persistent ctrl-surface state

Keep latest surface configuration, regardless if surface is active
or being deactivated. Current state after de-activation is retained.

Currently state loaded from a session overrides global state from
global preferences, if the surface is marked active in the session.
This is to allow midi-learn.

generic-midi and session-specific midi-learn will require additional
work.
