Improved widgets branding

We've continued working on the website branding configuration to keep enabling you to build widgets that match your brand with even more ease. The configuration options became more straightforward and now better reflect how is every option going to be used.

You're now also able to parse branding from your website. It will try to parse all of the necessary colors and fonts (if available on Google Fonts or uploaded by you). Make sure to double-check every option after parsing to make sure everything is going to look correctly once you will be building your widget inside the widget builder.
