NEW FEATURE: ITEMIZED PAYPAL CART!

Supported OpenCart Versions:
================
All v1.4.x & 1.5.x versions

What does it do:
================
This contrib adds support for «PAYPAL ADVANCED» payment integration from PayPal.
This is a $5/month credit card processing option from PayPal.
It allows the use of iframes to let the customer stay on your site to pay, or redirect to the paypal site to pay.
Both can be done under the protection of paypal’s secure servers.
If using the iframe option, the process is seamless and customers get to enter card data directly on your site.

Notes:
================
At the time of writing, Paypal Advanced it only available in the USA & Canada
Other countries may be able to use their Paypal Pro Hosted alternative which I also have an extension for here:

Requirements:
==============
* You will of course need to have a Paypal Advanced Account.
* If using the iframe option, you will likely want to have an SSL certificate to avoid the «Mixed Content» warnings that browsers show.
This happens if your site is unsecured and the iframe paypal site is secured. If you do not have an SSL, then you can still use iframe mode, but customers using Opera or IE will see a warning about leaving a secured area. Or you could opt to use the redirect mode which should not have this warning. There is nothing I can do about this as it is just how the internet works.

Main features:
==============
* Paypal only charges $5/month for this service
* Itemized Paypal Cart ***NEW***

* No core files overwritten
* PCI Compliant since no sensitive data is collected on your site
* Debug Mode (logs debug info to your system error log for troubleshooting)
