As of version 1.1.2, Propane will load and execute the contents of
~Library/Application Support/Propane/unsupported/caveatPatchor.js
immediately following the execution of its own enhancer.js file.
You can use this mechanism to add your own customizations to Campfire
in Propane.
Below you'll find two customization examples.
1 - A responder that adds avatars to your chat view
2 - A responder that displays CloudApp images inline
