Add @:structInit to Style

[kevinresol]

This is a breaking change. But I doubt anyone will manually construct a Style.

[ianharrigan]

So when structInit is used you HAVE to init it this way? Ie, you can never new Style()?

As you say, i doubt anyone would new Style() and if they do, i think the structure initialization is better anyway

you can never new Style()?

you can't. compiler will generate an implicit constructor, but you can't call it manually.
