Need (@else if) and boolean variable support

[asifshirazi]

I'm converting my sass mixins library into postcss, but not possible yet:

@define-mixin center $horizontal: true, $vertical: true {
    position: absolute;
    @if $horizontal || $vertical {
        top: 50%;
        left: 50%;
        transform: translate(-50%, -50%);
    } @else if $horizontal {
        left: 50%;
        transform: translate(-50%, 0);
    } @else if $vertical {
        top: 50%;
        transform: translate(0, -50%);
    }
}

@asifshirazi I have a pr that will fix this. It has to do with the order in which the processors are called.

@etanlubeck were you going to make the PR?

[etnlbck]

I fixed this one in a different PR that we closed

[jonathantneal]

So we now have @else support? What about boolean?

[etnlbck]

nvm. i just looked at the example. we should re-open this issue. i'll submit a PR this evening after work.

[jonathantneal]

I think we support @else but not boolean, so did you want to make a PR or shall we close this issue, and you could open one for boolean support?

[jonathantneal]

We have else support so I am closing this. Feel free to re-open if you find something.
