Sets text to be displayed in @entry when it is empty and unfocused.
This can be used to give a visual hint of the expected contents of
the #GtkEntry.
Note that since the placeholder text gets removed when the entry

is given the initial focus in a window. Sometimes this can be
worked around by delaying the initial focus setting until the
first key event arrives.
