    Use fallback for symbolic icons
    
    * examples/book/actionbar/examplewindow.cc: Don't use magic number for
    icon size. Allow fallback icons when using symbolic icon names.
    * examples/book/headerbar/examplewindow.cc:
    * examples/book/popover/examplewindow.cc:
    * examples/book/searchbar/examplewindow.cc: Allow fallback icons when using
    symbolic icon names. Some icon themes lack symbolic icons. Bug #723124.
