0.9.1

• Fixed support for vendor directories outside of the theme root (props @elvishp2006).
• Removed explicitly copied image files from the build step - image files that are not used in any css file should be explicitly imported in js/css for them to be included in dist/.
• Fixed .ico and .gif files not being included in build step.
• Added eslint (props @elvishp2006) and stylelint (props @paulomfr) - check out the new Yarn Scripts documentation article for more information.
• Added an example theme screenshot.
• Significant improvement in documentation coverage (there is still a lot more to be done).
