New Feature: being able to sign a petition with an account

[Te-k]

Is your feature request related to a problem? Please describe.

Today, even if you have an account you have to provide personal information to sign a petition. It would be really interesting to be able to sign a petition with an account, especially for multi-user/org instances.

Describe the solution you'd like

When you are logged in, replace the signature view with a button "Sign". Not sure how to implement that server side.

I think server-side, it would be a method on the Signature model Manager, that would take a User and create a new Signature from its information.

See https://docs.djangoproject.com/en/2.2/topics/db/managers/#adding-extra-manager-methods

what do you think about filling signature form with connected user infos ?

I think it's great, except maybe it can scare some users off because "why is my personal data already entered ?! I am being tracked or what ?!" But I guess if it's a problem we can always improve the UI to explain where this data comes from.
