webpack css/less/scss setup is imcomplete

[3cp]

According to aurelia-cli, need at least following to support resources.

{ test: /\.(png|gif|jpg|cur)$/i, loader: 'url-loader', options: { limit: 8192 } },
{ test: /\.woff2(\?v=[0-9]\.[0-9]\.[0-9])?$/i, loader: 'url-loader', options: { limit: 10000, mimetype: 'application/font-woff2' } },
{ test: /\.woff(\?v=[0-9]\.[0-9]\.[0-9])?$/i, loader: 'url-loader', options: { limit: 10000, mimetype: 'application/font-woff' } },
// load these fonts normally, as files:
// (url-loader also works for these fonts)
{ test: /\.(ttf|eot|svg|otf)(\?v=[0-9]\.[0-9]\.[0-9])?$/i, loader: 'file-loader' },

Need some study on the above snippet.

It also need /\.css$/ rule to support both css and scss when scss is selected. Same goes to less.
