Bring back Fast-Track with yummy assets and animations.

Fast-Track had been quite neglected, so brought it back up
to speed with ContactsContract changes.  Also rearranged
the Action launching logic to use ContactsSource.DataKind
for any icons and label generation.  Wrote slide animation
that looks awesome.

Added Fast-Track triggering to normal contacts list, since
it has photos now.  Also supports being launching in various
modes, which for now are three sizes.
