Update to 1.14:

1.14  Wed Sep  4 13:44:00 2013
- Document the copy() method.
- Patch the copy() method so it respects the {no_attribute_copy => 1} option.
- Add method read_tree(), for text files. It uses Perl6::Slurp (which supports utf8).
- Add methods read_attributes() and string2hashref($s) for use by read_tree().
- Add t/read.tree.t to test read_tree().
- Add t/tree.utf8.attrbiutes.txt, in utf8, for use by t/read.tree.t.
- Add t/tree.with.attributes.txt and t/tree.without.attributes.txt for use by t/read.tree.t.
- Make Perl V 5.8.1 a pre-req so we have access to the utf8 pragma.

1.13  Mon Aug 12 17:16:00 2013
- Change the values accepted for the no_attributes option from undef and 1 to 0 and 1.
If undef is used, it becomes 0, so pre-existing code will not change behaviour.
This makes it easier to pass 0 or 1 from the command line, since there is no default value available.
