Allow to get Color from Analysis

[romanzes]

The idea is to use it like this:

let attrs = analysis.extra_attrs();
for attr in attrs {
    let class = attr.get_attr_class();
    let attr_type = class.get_type();
    match attr_type {
        AttrType::Foreground => {
            let color_attr = pango::AttrColor::from(attr);
            let color = color_attr.get_color();
            println!("red color {:?}", color.red());
        }
        _ => {}
    }
}

Need a hand in here?

Ok, I updated the code. The Attribute API is a nightmare...

[GuillaumeGomez]

Updated.

I tried to look at code again after long time, and now I can't find way to "get Color from Analysis" 😢 so I prefer postpone PR

[GuillaumeGomez]

You can't, that's the whole point. But at least you can now create all available attributes.

[EPashkin]

Then maybe remove changes in analysis.rs and Gir.toml. Or user can do something significant with Vec<Attribute>?

This we have constructors and minimal get/set for Attribute (API really strange) and getters for PangoColor.

That's a good point. The PR as it is now does not even implement what the title says :)
