Galette

Currently, there is no state of paid contribution into Galette. Ones created from the Paypal or Stipe plugin are already paid, while we have no idea for all other payment types.

We could add a is_paid column in database, with the corresponding checkbox on contributions form.
- Since we do not have any information, default value will be "not paid".
- Paid status should be changed from massive changes on contributions.
- Maybe a parameter to set the default to paid or not paid in preferences can be added.
