Iteration on fast-track to show better data and disambig.

Finished up code that allows for disambiguation between
multiple contact methods under same mime-type.  Per design,
the fast-track window expands to show all choices when there
are multiple available.  For example, it shows a list
between "Home", "Work" and "Mobile" if an aggregate has
three phone numbers.  Back key will first dismiss the
disambig list if shown, before dismissing the dialog.

Moved fast-track to use Rect target areas to be more
flexible, instead of splitting up into multiple variables.

Correctly measure the fast-track window now, instead of
relying on hard-coded constants.  Now using the new query
path provided by SocialContract to provide single-line
social summary for a given aggregate, instead of using
hard-coded social string.

Added a third data query to pull display name for aggregate
along with most-present presence from provider.  Changed
fast-track to make chicklets focusable for dpad navigation.
