Action history log for the entire Madgicx app

After discussing this with Yahav, we'd like to build a history log for the entire Madgicx app to show all the actions taken by users in the account. What triggered this was this feature request: This is so we can track who are making changes and updates on the ABO for a specific ad account. Madgicx Field - PLEASE PICK ONE!: abo Issue Category: Enhancement Summary (Short Description): Show who created/set up the ABO, who made changes and which changes, who turned off/on, etc. User ID: 161107 Reported By: Wella Torre
