Problem with lack of extra option support for CSS/LESS loaders

[fguitton]

SpinJS does not allow the addition of extra option (similar to babelConfig/webpackConfig) for CSS/LESS loaders leading to the following error when we bump the version of the less package to 3.0.0 :

ERROR in /mnt/c/Repos/apollo-universal-starter-kit/node_modules/css-loader??ref--7-1!/mnt/c/Repos/apollo-universal-starter-kit/node_modules/postcss-loader/lib??ref--7-2!/mnt/c/Repos/apollo-universal-starter-kit/node_modules/less-loader/dist/cjs.js??ref--7-3!../client/src/modules/common/styles/styles.less

It does not seem to be addressable by use of webConfig to merge with the final webpack configuration since the loader configurations are in anonymous arrays/objects.

If you have free time, please consider helping with implementation

@fguitton Implemented in #48 and published asspinjs@0.4.116, use cssConfig builder option to override generated css-loader options.
