Noah Petherbridge 38614ee280 Tighten Doodad JavaScript API, User Documentation
* Tightens up the surface area of API methods available to the
  JavaScript VMs for doodads. Variables and functions are carefully
  passed in one-by-one so the doodad script can only access intended
  functions and not snoop on undocumented APIs.
* Wrote tons of user documentation for Doodad Scripts: documented the
  full surface area of the exposed JavaScript API now that the surface
  area is known and limited.
* Early WIP code for the Campaign JSON
