ERP5Security: Introduce to JSON Web Token Authentication Plugin

ERP5Security: A small introduction to JSON Web Token Authentication

ERP5Security: Expand JWT to add and process extra data while verifying password

ERP5Security: Use processDataScript to validate user + clean code

ERP5Security: Improve JSONWeb Token, do not set cookie on all request and handle bad signature

ERP5Security: JWT Token uses HTTPOnly and Secure cookies

ERP5Security: code improvments to ERP5JSONWebTokenPlugin

ERP5Security: JSONWebToken Plugin use Timed Token

+ Various Code improvment

erp5_officejs: Data is editable on spreadsheet only if it is the correct type else HTML preview is provided

ERP5Security: Add testERP5JSONWebTokenPlugin

ERP5Security: JSONWebTokenPlugin do not depend on python scripts + code improvments
