This already worked only within site offers by way of default model
ordering. Site offers are probably the most common offers, however the
ordering of all offers has to be controlled by the applicator.

Cherry-picked from #1414.
Hmmm, this turned out to be a monster commit. This change allows the
basket to be able to correctly calculate prices including tax.
It also requires a whole load of test changes since all baskets now
require a strategy instance to be assigned.
This allows updating code in both places, if necessary. Getting Django
1.5 support would be painful otherwise. This also removes the circular
dependency of django-oscar-testsupport on Oscar.
The requirements were merged. The imports were updated
accordingly. Unused imports in the touched files were removed. No
further changes.
