Create new theme to replace Canvas

[bobbingwide]

Canvas is being replaced by Storefront. We need to create a new child theme using Storefront as the template.

Requirements

• Support shortcodes
• Support checkout customisations - currently implemented using a plugin
• Needs custom CSS for responsive styling of extension plugin components.
• Needs custom CSS for styling on the iPhone 4S and other small devices

If required,

• Support caching and optimisation plugins

The only shortcode that needed support was [box]. Rather than use the plugin I copied the code for this shortcode to functions.php.
I wrote some fix up code to remove the shortcode from products. But the fix up also needs to remove it from product categories.

Checkout customizations were implemented using the WooCommerce Checkout tab in Customiser.
