* New "X" button appears in the system bar, allowing the
user to clear all notifications. Only appears when the
notifications list is showing and there are clearable
items. (Note: the textual button on phones has also been
replaced with an X.)
* Updated panel background artwork and positioning.
* Removed a bunch of old art.

1. Added content description to pretty much all animals
in the zoo including buttons in the navigation bar,
notifications and status icons for battery, signal,
data, etc.
2. Rectored to avoid ovelaying views since they block
touch exploratino. In general overlaying views
cause trouble for touch exploration and accessibility
in general.
3. Avoid sending accessibility events in case the user is
touching outside of the StatauBAr panels to avoid
confusion.
4. Added records to accessibility events in the places where
this would help the presentation. So the event comes from
a given "leaf" view and its predecessor is adding a record
to the event for itself to provide more cotext. It is up
to the accessiiblity service to choose how to present that.
