Show correct activated/selected effect for lists

- copy system assets for activated/selected states to the project
-- rename existing list_pressed_holo_light to
   action_bar_item_pressed_holo_light since the name is not
   appropriate and used by system assets.
- use white color for activated/selected texts
- make ContactListItemView show "pressed" effect correctly
-- "activated" background should not be shown when the item
   is not activated. If it shows it, "pressed" effect is hidden
   by the wrong background.
-- The background itself is needed to not highlight section
   headers.
-- manually call setActivated() toward children. Without it,
   they look "black" on the first app boot.
- remove an animation parameter for ContactListItemView's
  "activated" background. The animation makes the whole item
  flicker.
