[Phone] Fix layout for phone favorite screen

- Have additional padding between headers
- Use blue color for filter header in phone favorite
- Have bigger texts for A-Z section header
- Have photos on left in "phone search" screen
- Add "New Contacts" menu in favorite screen

Because LayoutFilter isn't ready on Fragment#onAttach(),
we need to have initAdapters() on onCreateView(), which looks
strange. However it will need much work to move every layout
logic to PhoneFavoriteMergedAdapter, let's just have a TODO
for that.
