Extend NSDate such that it behaves like DateInRegion for the default or local region

[Hout]

Write the NSDate extension such that it behaves like DateInRegion for the local or default region. E.g.

nsdate = NSDate()
regionDate = nsdate.inRegion(defaultRegion)

// Now nsdate and regionDate would behave equivalent

This would make the library easier to use if no conversions to other locales, time zones or calendard are necessary.
It would also make migration from SwiftDate 1.2 easier.

I agree, but adding inDefaultRegion() to isn't that bad anyway.

Fixed in v3.0.0
