Add a new example app Add a new example to the getting started part of the docs. The focus of this example is on 'new stuff': GtkApplication, templates, settings, gmenu, gaction, GtkStack, GtkHeaderBar, GtkSearchBar, GtkRevealer, GtkListBox, GtkMenuButton, etc. It is being developed in several steps. Each step is put in a separate directory below examples/: application1, ..., application8. This is a little repetitive, but lets us use the code of all examples in the documentation.

Another round of template binding api changes We rename the gtk_widget_class_bind_template_child{_internal} macros by appending a _private to their name. Otherwise, it would be too magic to pass the 'public' names as arguments, but affect a member of the Private struct. At the same time, Add two new macros with the old names, gtk_widget_class_bind_template_child{_internal} that operate on members of the instance struct.
