New Feature: Add-on products

Several vendors have pointed out that there are certain products on Hotel Tech Report that can't be purchased al-a-carte. For example, a booking engine that is sold with a PMS. (special shout out to William @ Net Affinity for the initial feature request 👏)

The Problem is that these add-on products can be mis-leading to buyers as they are not standalone products.

The Solution is the new 'add-on' products feature where HTR will designate products that are add-ons clearly throughout the site UI for buyers.
