* search on code first to match tax codes
The tax code code should be more discriminant that the tax code name.
* compare more fields in tax codes
* deletion of tax codes removed from templates
For tax codes, it make sense to propose deletion, since tax codes
are normally defined by the tax authority and the user does not
customize them.
* update accounts on taxes even if an update of the account was not requested
Useful when the chart of taxes changes but the chart of account
need not be updated.
* depth-first search of tax codes
This helps creating parents before children.
* compare more fields in taxes
* add active field on tax code
Deactivate tax codes which are not in the template.
* deactivate taxes that are not in the template
* multi-company criteria for taxes
* avoid inserting duplicates in presence of inactive taxes or tax codes
