Approval tool for new DFP AdUnits for NextGen auditing

We need to approve a lot of new ad units for DFP that are formatted specifically for auditing purposes. 

The interface for doing this within DFP is not rich enough to filter out the relevant ones safely, so I built this tool to help out. 
normally when you see `option.isDefined` what you really want is...

    flash.get("success").map{ success =>
        <div class="alert alert-success" role="alert">@success</div>    
    }
