Claudio Saavedra e4a83370c4 Improve the looks of the license text in GtkAboutDialog 
It is not safe to assume that copyright text in applications is
one liner, therefore it's better to split it from the program name.

Also, the license text should be in a paragraph of its own, so
add an extra '\n' above it.

/**
* SECTION:gtkaboutdialog
* @Short_description: Display information about an application
* @Title: GtkAboutDialog
* @See_also:#GTK_STOCK_ABOUT
*
* The #GtkAboutDialog 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.
*
* About dialog often contain links and email addresses. #GtkAboutDialog
* supports this by offering global hooks, which are called when the user
* clicks on a link or email address, see gtk_about_dialog_set_email_hook()
* and gtk_about_dialog_set_url_hook(). Email addresses in the
* authors, documenters and artists properties are recognized by looking for
* <literal>&lt;user@<!-- -->host&gt;</literal>, URLs are
* recognized by looking for <literal>http://url</literal>, with
* <literal>url</literal> extending to the next space, tab or line break.
*
* <para id="gtk-about-dialog-hook-setup">
* Since 2.18 #GtkAboutDialog provides default website and email hooks that
* use gtk_show_uri().
* </para>
*
* If you want provide your own hooks overriding the default ones, it is
* important to do so before setting the website and email URL properties,
* like this:
* <informalexample><programlisting>
* gtk_about_dialog_set_url_hook (GTK_ABOUT_DIALOG (dialog), launch_url, NULL, NULL);
* gtk_about_dialog_set_website (GTK_ABOUT_DIALOG (dialog), app_url);
* </programlisting></informalexample>
* To disable the default hooks, you can pass %NULL as the hook func. Then,
* the #GtkAboutDialog widget will not display the website or the
* email addresses as clickable.
*
* To make constructing a #GtkAboutDialog as convenient as possible, you can
* use the function gtk_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 #GtkAboutDialog, as shown in the following example:
* <informalexample><programlisting>
* gtk_show_about_dialog (NULL,
* "program-name", "ExampleCode",
* "logo", example_logo,
* "title" _("About ExampleCode"),
* NULL);
* </programlisting></informalexample>
* Note that prior to GTK+ 2.12, the #GtkAboutDialog:program-name property
* was called "name". This was changed to avoid the conflict with the
* #GtkWidget:name property.
