Adopted SocialContract and first pass at fast-track.

Showing live data from SocialProvider through recently added
SocialContract constants, symlinked for now since the contract
isn't in the framework yet.

Added first pass at fast-track using edge-based triggering
from the social list.  Wraps the ListView in a EdgeTriggerView
that watches for "pull" actions from a specific edge.  Also adds
concept of a FloatyListView to keep a "floaty" window anchored
with respect to ListView scrolling.

The fast-track window summarizes contact methods based on
anyone system-wide who offers an icon for the mime-types.  For
example, the testing app pushes app-specific contact methods
into the Data table, and then provides icons through its
RemoteViewsMapping XML resource.

Changed SHOW_OR_CREATE to accept Aggregate Uris and now shows
fast-track in cases where a single matching aggregate is found.

Abstracted AsyncQueryHandler to a QueryCompletedListener callback
interface to clean up code that uses it while still protecting
against leaked Contexts.
