commerce 8.x-2.0-beta7

Major changes:

- The checkout sidebar can now contain panes.
- The checkout complete page is now powered by a Twig template ('commerce-checkout-completion-message.html.twig')

- Major work on promotions:
1) Refactored and simplified API
2) Redesigned UI (listing, add/edit form)
3) Basic compatibility settings (Any promotion / Not with any other promotions)
4) New usage API (track and limit usage per promotion and per coupon)

The redesigned promotion add/edit form. Click to expand.

- Brand new Tax submodule:
1) Supports entering prices with or without tax
2) Supports tax registrations (collect tax from other countries based on a store setting)
3) Remote (allowing for Avalara, Taxamo, etc) and local tax type plugins
4) Custom tax type plugin which allows entering multiple rates and specifying a zone
5) EuropeanUnionVat tax type plugin with predefined rates for all EU countries, and physical VS digital logic.
6) Tax rate resolvers (choose a reduced rate / no rate for specific order items, etc)
This replaces the tax code that was removed before beta1, rewritten for optimal performance and more features.
