ant task for stylesheet clouser about closure-stylesheets HOT 2 OPEN

This would be very helpful. While I prefer the closure ant configuration with fine grained
settings per group, it might also be worth taking a look at the wro4j config where
you can specify css and js resources in a single group. As well as refer to other groups.

    <group name="base">
        <css>/path/to/file.css</css>

        <js>/path/to/file.js</js>

        <group-ref>other</group-ref>
    </group>
