* libnautilus/gtkflist.c, libnautilus/gtkflist.h: Rename
	"row_popup_menu" and "empty_popup_menu" signals to
	"context_click_row" and "context_click_background" for more
	consistency with the way the icon container does it. Removed
	GdkEvent parameters from these signals. Added an int indicating
	the row right-clicked.
	(gtk_flist_button_press): Do not change the selection to the row
	that gets right-clicked. It was inconsistent with the icon view
	and most of the known universe.
