Standard favicon.ico icon
Add utility functions to include a favicon.ico image on the standard CherryPy distribution, making easy for native CP2 applications to use it. The icon is stored into a plain Python file, encoded with base64. A utility function can be used to send it as a response, with all headers set correctly. The user only needs to capture the cpg.root.default() method, check the path for favicon, and call the function.
