Site Assist Pro, CSS Menu Writer, Palette Picker, Surveyor, Data Bridge, eCart, Social Media Toolkit and PayPal eCommerce Toolkit.
My mistake, I was looking in the CS 5.5 directory initially. Also, the recommended legacy files were uninstalled prior to the installation of DataBridge.
However, I just looked in the CS 6 directory and all of the files are present - including the ButtonStylerShared.js. Here is my current structure:
