[gnome-maps] Add PlaceFormatter class

[Jonas Danielsson <jonasdn src gnome org>]

commit 95576d3b3c5b44152a359b31913cce848ab5b38e
Author: Damián Nohales <damiannohales gmail com>
Date:   Sun Oct 12 15:19:08 2014 -0300

    Add PlaceFormatter class
    
    The purpose of this class is to get the relevant GeocodePlace properties
    for the available place types. The class is implemented to be UI
    agnostic, so it can be reused in many parts of Maps.
