Added GtkBuildable support for adding rules to GtkRecentFilter

Browse Source 
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 Short_Description ##### -->
A filter for selecting a subset of recently used files
<!-- ##### SECTION Long_Description ##### -->
<para>
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()).
</para>
<para>
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/*.
</para>
<para>
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().
</para>
<para>
Recently used files are supported since GTK+ 2.10.

* <para>
* The GtkRecentFilter implementation of the GtkBuildable interface
* supports adding rules using the &lt;mime-types&gt, &lt;patterns&gt and
* &lt;applications&gt elements and listing the rules within. Specifying
* a &lt;mime-type&gt, &lt;pattern&gt or &lt;application&gt is the same
