Call any ActiveCampaign API from App Studio

A new feature has been added to App Studio! The !http command now has a target property that can be used to change the behavior of an HTTP request. Setting this property to "activecampaign" will enable your application to make any API request to the current ActiveCampaign host! For backwards compatibility, the default value of the target property is "connection". For more information, read the Commands and Variables documentation.
