[DBTech] DragonByte eCommerce

[DBTech] DragonByte eCommerce 2.3.0

Update highlights

The most important part of this release is: This product now requires PHP 7.3. This is a requirement set by one of the most important 3rd party libraries used by eCommerce, so it's entirely outside of our control. This library has had an important update that needed to be included in a release prior to Jan 1st 2021.

Please be aware that if you are not able to update to PHP 7.4 yourself, you should contact your web host and ask them to assist you with upgrading.
PHP 7.2 has been officially declared end-of-life and no longer receives security updates. Continuing to run PHP 7.2 may expose your website to unpatched security vulnerabilities or exploits.

The U.K. will no longer be classed as an EU country as of Jan 1st 2021, and its sales tax rate will no longer be automatically updated past that date.

This version also improves database query performance of the release / download lists in the front-end, meaning the functionality will scale better when you have a lot of releases available.
