Allow custom name for style

[martin-kolarik]

Simple change adding variant into class! macro. The purpose is to ease development/debugging in browsers' devtools, where customized style names are far more descriptive.

I like the idea, but I don't like the syntax:

class! { "foo"
    .style("background-color", "green")
}

Maybe it could use this syntax instead?

class! {
    #![prefix = "foo"]
    .style("background-color", "green")
}

Or possibly this syntax:

class!("foo", {
    .style("background-color", "green")
})

Definitely, the syntax is up to you, thanks. So, should I modify my PR?

[Pauan]

Yes, please. Since it's for debugging, I think the #![prefix] syntax is probably the best.

Thanks!

That was fast! I haven't managed to comment anything :-).
