Report DateTime validation errors relative to caller, not the point at which DateTime was called.
Add missing DateTime methods, and xt/author/interface_coverage.t to ensure the interface stays complete.
Require DateTime 1.53 for all the additional methods. Thanks to Slaven Rezić, not only for running the CPAN tester that found the problem, but filing an RT ticket on it. CPAN TESTERS ROCK!
