Theme settings need cleanup

[Cam]

The theme settings have reverted to an old version. We'll need to manually clean them up for the new methods.

Theme info proposal;

 {
    "name": "theme_info",
    "theme_name": "Concrete",
    "theme_author": "Elkfox",
    "theme_version": "2.0.0",
    "theme_documentation_url": "https://elkfox.github.io/Concrete/",
    "theme_support_email": "help@elkfox.com"
  }

Do we remove the color options? I feel like changing colours won't be used by most merchants. The settings should all be merchant focused really.

Yeah I think so. There should be minimal colour config available in the base framework.
