Native Swift support

[larryonoff]

Hello Matt,

Are you going to implement this library natively on Swift?

I use this library in Swift project and there're several common Swift to Objective-C inconveniences, e.g.

for object in element.childrenWithTag("td") {
   let child = object as! ONOXMLElement
   ...
}

NSFastEnumeration cannot be used in for-in directly

- (id <NSFastEnumeration>)CSS:(NSString *)CSS;

most methods return ImplicitlyUnwrappedOptional

I can update the code base at least to use Objective-C Nullability.

Please comment.

Hi, @larryonoff

@mattt seems to be too busy to login github to look at these PRs and issues for the recent few months, and I have just ported Ono to Swift with some redesign following common swift convention, as well as some bug fixes. All tests in Ono passed.

I will be actively maintaining the library so I'll be glad to have your feedback if you would give it a try ;)

@cezheng thanks!

Apologies for not responding sooner, @larryonoff. Just wanted to let you know that Ono now has nullability annotations that should make inter-op with Swift much nicer. If you see any other opportunities to improve things, please let me know!

@mattt thanks!
