Remove some cruft.
General reformatting. I know.. I know..
Be consistent about tab spaces.
Revert back to old calc for promotions. Still some work to do here, but this is closer.
This fix may not be compatible with other uses of spree_tax_cloud.

I've changed the tax calculation to not include shipping. TaxCloud seems to do a proper job
of calculating tax without this, at least in my use case. Open to other ways to make this a
more portable change.

Also removed some unused methods in the order_decorator. I may regret that later but it
has helped me understand this code better.
Catch and handle failed address verification.
Updates for Spree 2.0 & Making RSpec actually run.
