Title: NLTK API tweakage.

When I tried to use the Python ParsingShell I had errors that seem to be due to an API change in NLTK. nltk.tree.Tree.parse has apparently been removed/replaced by fromstring. There is bracket_parse too but its code says don't use it. Don't know if this is backward compatible but it works for me.
