Updates fragment dejunk

- Reuse stream item views.  Simplified the view layout for this.
(In this CL we still inflate views, rather than creating them in code.
Even without doing that performance now seems good enough.)

- Decode HTML into CharSequence in ContactLoader
- Removed ContactTileImageContainer and created
LayoutSuppressingImageView and LayoutSuppressingQuickContactBadge
