Account - Public Invoice

This package includes a new Invoice Page. This is only accessible to logged-in customers.
A new Template file for account_history_info.php that shows a button link that goes to the invoice for that order AND opens their browser print dialog to Print or Save as PDF. This works in most browsers Chrome, Edge, Safari, Firefox.
This makes it very easy for customers to see their Order Invoice and print or save it all in one click.
The new Template file for account_history_info.php also improves the Order History display (see images).
The module also includes the language files.
Installation Readme included.

Text shown can be changed in the language files.

Tested on CE Phoenix Cart v.1.0.8.8 - 1.0.8.20 with PHP 7.4 - 8.2 but may work on earlier and later versions.
