What this does
---
 - This make a custom table view cell for the category table. Please note, the images are place holders for now.
 - This replaces the default title bar, and integrates the Testasaurus colour scheme and UI into the custom title bar.
 - This allows enabling mouse tracking in a header view (custom title bar) for moving the window.
