Updated devel/p5-Tree-Simple to 1.31
------------------------------------
1.31  2017-04-17T09:11:00
 - Add 3 new methods: getSiblingCount(), isFirstChild() and
   isLastChild().  Warning: getSiblingCount() does not include the
   invocant, unlike getAllSiblings().
 - Add t/24_Tree_Simple_sibling_test.t.
 - These methods are used by Tree::Simple::View::HTML V 0.19 to output
   HTML compatible with the HTML5 standard for nested lists. See
   https://www.w3.org/wiki/HTML_lists#Nesting_lists.  Thanx to
   Ekkehard Plicht for suggesting this, and for the patches, which I
   have reworked.  See RT#121099.
