Organization 2.0 "👍"

The Organization module is where Woba’s customers set up their organization, with its departments, managers, and employees.

The purpose of the new version, Organization 2.0, is three fold:

1. Upgrade the frontend to match the new visual design.
2. Implement Organization Versioning, so we know what a complete organization structure looked like at a certain point in time.
3. Include the new Excel Uploader (which was created for 3, a telecom company, to enable us to not only import employees, but also departments) in the frontend, so customers can start using it.
