LocalDate::now($timezone /*= system TimeZone*/)

[nkamuo]

The LocalDate::new(), LocalTime::new() and LocalDateTime::new() all require the timezone parameter.
It would be a lot easier to use if the ::now() method's timezone parameter is optional and defaults to the configured php TimeZone.

that's kinda what I'm referring to in #111

Making it easier to use generally.
