This commit improves the payment terms by:
- making the payment terms lines editable on-the-fly removing the need for a wizard
- refactoring the computation of the payment terms
- adds new demo data for payment terms
- adds an example section where the user can test and preview the due dates and amount of its payment terms
- adding a new parameter "Display terms on invoice". If set, the payment deadlines and respective due amounts will be detailed on invoices.
The refactoring:
- adds a field `months` (months to add after the invoice date)
- adds a field `end_month` (if True, switch to the end of the month after having added months or days)
- renames the field `day_of_the_month` to `days_after` (days to be added after the switching to the end of the month, only if `end_month` is set)
- deletes the field `option` which was too restrictive
- modifies the calculation of the payments terms taking into account these new fields
This allows some combinations that were not possible before.
Example: The French payment terms "30 jours fin de mois le 10" (which should be interpreted as "10 days after the end of the next month") can be encoded as
```
months = 1
days = 0
end_month = True
days_after = 10
```
