* = gamification, test_website, stock
- KarmaError is now handled as a 400 exception.
- test_website has been updated.
- NO_POSTMORTEM is now clean it was referencing duplicates as most the
exceptions inherit from except_orm.
- serialize_exception from http.py has been moved to ir_http
to take advantage of the odoo inheritance system. We can then
extend ir_http serialize_exception method to add the KarmaError
logic if and only if gamification is installed.
Places where serialize_exception was previously used are updated.
