Stop cursor blinking after a configurable timeout. (#353670, #352442,

Browse Source 
Stop cursor blinking after a configurable timeout.
	(#353670, #352442, Arjan van de Ven, Manu Cornet)

	* gtk/gtksettings.c (gtk_settings_class_init): Add a
	gtk-cursor-blink-timeout setting, which specifies the number
	of seconds that the cursor should blink after a user interaction.
	The default value is G_MAXINT to preserve the current behaviour.

	* gtk/gtkentry.c (blink_cb): Stop blinking after blink-timeout
	seconds.

	* gtk/gtkentry.c (gtk_entry_completion_key_press)
	(gtk_entry_button_press, gtk_entry_focus_in): Reset the
	blink timer.

	* gtk/gtktextview.c (blink_cb): Stop blinking after blink-timeout
	seconds.

	* gtk/gtktextview.c (gtk_text_view_key_press_event)
	(gtk_text_view_button_press_event, gtk_text_view_focus_in_event):
	Reset the blink timer.
