Update sass options to new config object

[b12f]

Webpacks sass-loader migrated to a new version of the config object a long time ago. This now requires the includePaths to be set in the sassOptions map. When creating a new cycle project via create-cycle-app, the config error is the first thing that pops up when starting the project.
