[Icon|Button] Make action available on icon and use keyb name.

You can now bind a key-binding on mouse click to icons and buttons by setting
"action" property.

For example:

```css
icon-paste {
    expand: false;
    filename: "gtk-paste";
    size: 24;
    vertical-align: 0.5;
    action: "kb-primary-paste";
}
```
