Shipping Tax

[duncanmcclean]

This pull request closes #856 by allowing for tax to be applied to shipping amounts. This was only made possible by changes to the calculator in #873.

By default, calculating tax for shipping methods is disabled (in both the Basic & Standard tax engines), however you may choose to enable them:

Basic Tax Engine:

To enable, you may simply flick the toggle in your Simple Commerce config:

// config/simple-commerce.php

'tax_engine_config' => [
    // ...
    'shipping_taxes' => true,
],

Then, the tax rate you set for all other products will be applied to shipping too.

Standard Tax Engine:

1. Upon upgrade, you'll find a new 'Default - Shipping' tax category
2. Configure tax zones & tax rates associated with the newly created category
3. Shipping taxes will be based on the rates entered

To Do

• Clean up documentation
• Resolve failing test
