Expose or add missing nux functions for a11y support

[David Barth]

From the a11y meeting notes:
 * nux integration (Jay)
  * requires focus mgmt support to be exposed (exists, but is not exposed)
  * key events being signalled
  * extra nux apis (lower priority, a factory mechanism works for now independently of nux)
  * should discuss refactoring that into nux later; but try to avoid coupling nux with unity, something more abstract (like the genereric introspection mechanism would sound better)

[David Barth (dbarth)]

At this stage, my understanding is that everything required has been landed in the last (big) nux release

[Launchpad Janitor (janitor)]
