Assetic config

config.yml

assetic:
    debug:          %kernel.debug%
    use_controller: false
    filters:
        cssrewrite: ~
        scss:       ~
        # closure:
        #     jar: %kernel.root_dir%/java/compiler.jar

        # yui_css:
        #     jar: %kernel.root_dir%/java/yuicompressor-2.4.2.jar

trying the YUI stuff tells me

Unrecognized options "jar"

I just sent @fabpot a pull request to fix this.
