DateTime-Format-Natural 0.28

on Perl CPAN

Moved timespan separator definition to language metadata
base classes.

scripts/dateparse.pl language chosen always defaulted
to 'en' irrespective whether another one has been chosen
or not. Changed it to only fallback to the default language
('en') if no other one has been provided.

Added t/03-parse_format.t to the testsuite which tests datestrings
with various differing format strings.
