Should source maps be cached?

[stevenvachon]

I'm trying to help debug an issue with using Webpack and Karma together. I'm thinking that it could be resolved if each cached module contained its inline source map (when devtool is "inline-source-map") to prevent Webpack from having to reevaluate. Would this make sense for cache-loader?

@stevenvachon could your issue be related to #70 ?
