In particular gtksettings.h and gtkstylecontext.h needed to be included
in lots of places now.
Also, I order the includes alphabetically in a bunch of headers.
Make page titles left-aligned again. Changing from misc alignment
to GtkWidget::halign here was a mistake. We can't do that for labels
in a size group, as long as labels still pay attention to misc
alignment.

This has mostly two advantages:
- the most obvious one is the theme can render a border around the
sidebar if it wants to.
- we also can avoid hardcoding a container border width for the sidebar,
and just use a padding from the theme. This also allows different
themes to define a different padding, etc.
The drawback is we must draw the background ourselves, but it's easy
enough.

GtkAssistant is widely recognized as a butt-ugly widget.
This commit changes its style to look more modern. We
deprecate the sidebar and header image properties and
don't show them anymore. Instead, page titles are arranged
in a sidebar, with the title of the current page shown
in highlighted style.
ATK provides macros to the same effect as G_DEFINE_TYPE; using these
macros has the advantage of removing tons of duplicated code and
reducing the maintainership burden.
The widgets with inline accessibility implementation should switch to
these macros, and clean up the code.

The custom page type will not show any buttons by default, and
it is left to the application to add its own buttons instead.
The _next_page() and _previous_page() functions can be used
for the back and forward buttons used by the application.

It doesn't make sense to keep them separate as GtkSizeRequest requires a
GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have
one without the other.
It also makes the code a lot easier because no casts are required when
calling functions.
Also, the names would translate to gtk_widget_get_width() and people
agreed that this would be a too generic name, so a "preferred" was added
to the names.
So this patch moves the functions:
gtk_size_request_get_request_mode() => gtk_widget_get_request_mode()
gtk_size_request_get_width() => gtk_widget_get_preferred_width()
gtk_size_request_get_height() => gtk_widget_get_preferred_height()
gtk_size_request_get_size() => gtk_widget_get_preferred_size()
gtk_size_request_get_width_for_height() =>
gtk_widget_get_preferred_width_for_height()
gtk_size_request_get_height_for_width() =>
gtk_widget_get_preferred_height_for_width()
... and moves the corresponding vfuncs to the GtkWidgetClass.
The patch also renames the implementations of the vfuncs in widgets to
include the word "preferrred".
- Add gtk_assistant_commit()
This function discards the visited pages list so the back button is not
shown on the current page, and removes the cancel button from subsequent
pages. Use this when information provided thus far cannot be revisited.
- Don't show the Forward button on a GTK_ASSISTANT_PAGE_PROGRESS if it's
the last page (according to the forward page function).
- Append a progress page to the GtkAssistant demo.
