Localized date functions

[dkirchhof]

Hello,

is there a reason, why the functions like toLocaleDateString don't except a locale string?
If there is no reason, I could create a PR with additional functions like toLocaleDateStringWithLocale or add optional params to the existing functions.

Cheers
Daniel

No, that's probably just an oversight. Please do PR that. Check the naming scheme for other similar functions and try to stick close to that.

Thank you for contributing!
