Update packages in generated projects

[luboskmetko]

Fixes #353

Also added eslint and stylelint as dependencies. Didn't update Gulp and Webpack to v4 as those produce some errors which require a more detailed look.

Hey, I looked briefly on packages with breaking updates (based on version numbers) and only thing I wonder is whether olegskl/gulp-stylelint#85 is still an issue?

[luboskmetko]

@jakub300 good call. Unfortunately, it's still an issue even in the latest 7.0.0 version, did a few tests with my test case here https://github.com/luboskmetko/test-gulp-stylelint

We could keep 3.9.0 version but that one uses stylelint v7.13.0 and there have been a lot of changes and fixes in stylelint since then (now at v9.1.3). Not sure if that causes any troubles in real projects, but we probably should think how to address this without relying on a fix in gulp-stylelint. Should we use some other plugin, eg the webpack one?

Could you try to go back to not working version and ignore vendor by passing it to gulp.src, something like:

gulp.src([path.join(src.base, src.styles), `!${path.join(src.base, 'styles/vendor/**/*')}`])

If it works I think it would be enough for us.

Actually, it's not only about vendor folder, users should be able to easily set specific folders to be ignored, for example whole src like described here https://www.getchisel.co/docs/development/code-quality/

It looks like you downgraded gulp-stylelint back to old version but stylelint v9 is still in dependencies

@jakub300 I've removed stylelint v9 from dependencies
