All ready for 5.3.3.x
A note: if you are waiting for this module to show up in the XC marketplace - it will not. XC denied the request to allow this module for sale on the marketplace. Looks like they don't want to encourage removal of XC branding and advertisement.
You can get it from my site - https://www.cflsystems.com/remove-branding-for-x-cart-5.html
