Release PHP-Parser 3.0.1

This was correctly done for the 'key'=>list() form, but not for
unkeyed nested lists.

+### Fixed

+* Fixed handling of nested `list()`s: If the nested list was unkeyed, it was directly included in
+  the list items. If it was keyed, it was wrapped in `ArrayItem`. Now nested `List_` nodes are
+  always wrapped in `ArrayItem`s.
