gtk/gtktree.lisp: Fixing string representations of tree paths.

  * The old ensure-tree-path returned a vector of strings, which is
    useless.  Fixed to return a vector of integers, using parse-integer.

  * Make tree-model-get-iter apply ensure-tree-path to its argument.

  * Enable ensure-tree-iter to coerce string representations of paths.
