Switch to Ubuntu Components 1.3

[Cosmin Humeniuc]

From https://lists.launchpad.net/ubuntu-phone/msg17337.html :
> Ubuntu Components 1.3 (more specifically, OTA7) introduced the
> ListItemLayout C++ component, that provides the developer with a tool to
> create performant list item contents to put inside the 1.2 ListItem. All
> apps using the old ListItems module (note, I'm not referring to the
> ListItem described above, but the old ListItems.Empty, ListItems.Standard,
> ListItems.Value ecc) should transition to the ListItem+ListItemLayout combo
> to enjoy more consistent UI, better performance and better code
> readability.
