What steps will reproduce the problem?
1. Put a favicon.ico/favicon.png in the root of your WordPress installation
or in your theme's folder.
2. Search the Sandbox source tree, e.g. `grep -HRn favicon ./`.

What is the expected output? What do you see instead?
I would expect Sandbox to support favicons like WordPress does by default.
However, it's not enabled.

What version of the product are you using? On what operating system?
I'm using Sandbox 1.6 with WordPress 2.7.1.
