Add an option to propagate node-sass error up to node process

[tk-o]

I use nvm and sometimes after changing NodeJS version, I am required to rebuild node-sass package in order to have it meeting current NodeJS version bindings.

I would like to be able to set build process the way, if there is any error coming from node-sass library, the build process is terminated (it's really handy while using this package in deployment pipeline).
