[REF] account: implemented new tax design and moved 'python tax' in an anciliary module
[REF] account: some refactoring made during the code review of compute_all on account.tax object
Merge branch 'master-account-new-api-mdi' into master-new-tax-design-fp2
[FIX] account: fixed the computation of taxes having include_base_amo unt set as True
[FIX] account, tax computation: fixed the subsequent use case by implementing that with tuple instead of list (mutable\!
) and doing so in compute_all() of account.tax instead of in account.invoice.tax object, which definitively makes more sense
[FIX] account: fixed duplication of tax and fixed the base amount that wasn't correctly set for tax included in price
[REF] account: refactoring made during code review
[FIX] account: fixed error introduced in previous commit
