libmate-desktop: Add MateAboutDialog class

This will allow MATE applications to use traditional About dialogs with GTK 3 (unfortunately completely different starting from GTK 3.12). This is just a fork of GtkAboutDialog of GTK 2.24, adapted to work with GTK 3 too.

+/**
+ * The #MateAboutDialog offers a simple way to display information about
+ * a program like its logo, name, copyright, website and license. It is
+ * also possible to give credits to the authors, documenters, translators
+ * and artists who have worked on the program. An about dialog is typically
+ * opened when the user selects the <literal>About</literal> option from
+ * the <literal>Help</literal> menu. All parts of the dialog are optional.
+ *
+ * To make constructing a #MateAboutDialog as convenient as possible, you can
+ * use the function mate_show_about_dialog() which constructs and shows a dialog
+ * and keeps it around so that it can be shown again.
+ *
+ * Note that GTK+ sets a default title of <literal>_("About &percnt;s")</literal>
+ * on the dialog window (where &percnt;s is replaced by the name of the
+ * application, but in order to ensure proper translation of the title,
+ * applications should set the title property explicitly when constructing
+ * a #MateAboutDialog, as shown in the following example:
+ * <informalexample><programlisting>
+ * mate_show_about_dialog (NULL,
+ * "program-name", "ExampleCode",
+ * "logo", example_logo,
+ * "title" _("About ExampleCode"),
+ * NULL);
+ * </programlisting></informalexample>
