[AsseticBundle] moved filters into individual config files which must be explicitly loaded

You must now explicitly load those filters you want to use in your app. Some filters have additional configuration options:

    assetic:
        filters:
            cssrewrite: ~
            yui_css:    { jar: "/path/to/yuicompressor.jar" }

You can also register your own filters now by referencing a configuration file:

    assetic:
        filters:
            my_filter:
                resource: "%kernel.root_dir%/config/my_filter.xml"
                foo:      bar

This configuration would load the referenced configuration file and set the "assetic.filter.my_filter.foo" parameter to "bar"
