Log:
* src/orca/settings.py: 
* src/orca/orca.py: 
* src/orca/orca_state.py: 
Added a ring buffer to keep references to accessibles and thus 
lengthen the lifetime of cached attributes (bug #491756).
* src/orca/focus_tracking_presenter.py: 
Use event.host_application whenever possible, minimize on
getApplication() calls (bug #491756).
