- The traceback is only visible if in debug mode or if edit mode.
- All except_orm exceptions are now displayed as a 400
but the AccessError wich is a 403. There is now a dedicted page
for the 400 error.
- Errors messages are no longer the exception args but its name if the
exception is an except_orm. Else there is no message since the current
logic override exceptions of type Exception in ir_http thus we have
no message to display.
