Remove deprecated warnings

[akitsu-sanae]

I removed Url.hx and Domain.hx's deprecation warnings.

before:

$ haxe build.hxml
src/js/node/Url.hx:61: characters 32-41 : Warning : This typedef is deprecated in favor of { ?slashes : Null<Bool>, ?search : Null<String>, ?query : Null<haxe.extern.EitherType<String, haxe.DynamicAccess<String>>>, ?protocol : Null<String>, ?port : Null<String>, ?pathname : Null<String>, ?path : Null<String>, ?href : Null<String>, ?hostname : Null<String>, ?host : Null<String>, ?hash : Null<String>, ?auth : Null<String> }
src/js/node/Url.hx:83: characters 91-100 : Warning : This typedef is deprecated in favor of { ?slashes : Null<Bool>, ?search : Null<String>, ?query : Null<haxe.extern.EitherType<String, haxe.DynamicAccess<String>>>, ?protocol : Null<String>, ?port : Null<String>, ?pathname : Null<String>, ?path : Null<String>, ?href : Null<String>, ?hostname : Null<String>, ?host : Null<String>, ?hash : Null<String>, ?auth : Null<String> }
src/js/node/domain/Domain.hx:34: characters 24-35 : Warning : This typedef is deprecated in favor of { domainThrown : Bool, domainEmitter : js.node.events.IEventEmitter, domainBound : haxe.Function, domain : js.node.domain.Domain }
$

after:

$ haxe build.hxml
$

related is #155

Well, this doesn't just remove deprecation warnings, it removes APIs people might still be using... So #155 seems like a better workaround.

I merged #155 instead.
