Remove syntax error
Take out 'with-sass' option as this is now going to be the default
behavior with 'grunt build'.
Give a background explaining the reason for the fork. Give better
details on developing an extension with this fork of the generator.
Remove info on 'grunt build --with-sass' as that is now the default
action for grunt build.
If you are using this fork you are wanting to use SASS, therefore,
create a default main.scss.
Change the package.json as this fork will be stand-alone and not merged
into the parent project.
