gtklabel.xml update

Hello,

Modified description to reflect the fact GtkLabel's have some alignment 
and padding control on their own. Let me know if this isn't the right 
way to submit changes.

     You can have control over the way a GtkLabel will be displayed with
     some methods such as <function class="GtkLabel">set_justify</function>

wish to

thing)
-    or padding for a GtkLabel, you can insert it into a
