Applications may want to present some folders in the places sidebar if
they could be immediately useful to users. For example, a drawing
program could add a "/usr/share/clipart" location when the sidebar is
being used in an "Insert Clipart" dialog box.
This function adds the specified location to a special place for immutable
shortcuts. The shortcuts are application-specific; they are not shared
across applications, and they are not persistent. If this function
is called multiple times with different locations, then they are added
to the sidebar's list in the same order as the function is called.
