Added GtkBuildable support for adding rules to GtkRecentFilter
Also added documentation section for this. Since the GtkRecentFilter
documentation was still living in sgml, as a side-effect I migrated these
docs to the gtkrecentfilter.[ch] sources.

+/**
+ * SECTION:gtkrecentfilter
+ * @Short_Description: A filter for selecting a subset of recently used files
+ * @Title: GtkRecentFilter
+ *
+ * A #GtkRecentFilter can be used to restrict the files being shown
+ * in a #GtkRecentChooser. Files can be filtered based on their name
+ * (with gtk_recent_filter_add_pattern()), on their mime type (with
+ * gtk_file_filter_add_mime_type()), on the application that has
+ * registered them (with gtk_recent_filter_add_application()), or by
+ * a custom filter function (with gtk_recent_filter_add_custom()).
+ *
+ * Filtering by mime type handles aliasing and subclassing of mime
+ * types; e.g. a filter for text/plain also matches a file with mime
+ * type application/rtf, since application/rtf is a subclass of text/plain.
+ * Note that #GtkRecentFilter allows wildcards for the subtype of a
+ * mime type, so you can e.g. filter for image/*.
+ *
+ * Normally, filters are used by adding them to a #GtkRecentChooser,
+ * see gtk_recent_chooser_add_filter(), but it is also possible to
+ * manually use a filter on a file with gtk_recent_filter_filter().
+ *
+ * Recently used files are supported since GTK+ 2.10.
+ *
+ * <refsect2 id="GtkRecentFilter-BUILDER-UI">
+ * <title>GtkRecentFilter as GtkBuildable</title>
+ * <para>
+ * The GtkRecentFilter implementation of the GtkBuildable interface
+ * supports adding rules using the <mime-types>, <patterns> and
+ * <applications> elements and listing the rules within. Specifying
+ * a <mime-type>, <pattern> or <application> is the same
+ * as calling gtk_recent_filter_add_mime_type(), gtk_recent_filter_add_pattern()
+ * or gtk_recent_filter_add_application().
+ *
+ * <example>
+ * <title>A UI definition fragment specifying GtkRecentFilter rules</title>
+ * <programlisting><![CDATA[
+ * <object class="GtkRecentFilter">
+ * <mime-types>
+ * <mime-type>text/plain</mime-type>
+ * <mime-type>image/*</mime-type>
+ * </mime-types>
+ * <patterns>
+ * <pattern>*.txt</pattern>
+ * <pattern>*.png</pattern>

+ * <applications>

+ * <application>glade</application>
