Subject: [PATCH] Set a pane title on the some a11y windows' root views

This allows a service to identify a window based on the title.
Configuration changes will restart the activity, losing a11y focus.
A11y focus may be retained by matching windows and unique ids. This
CL allows matching by window/pane title.

Test: manual
