Add original package template var to Product Upgrade/Downgrade page
As of right now the product upgrade/downgrade page passes a template var called $upgradepackages. That template var contains the details of the available packages that the client can upgrade too but there is no template var that contains details of the original package. We need a $originalpackage template var.
Reason this would be useful... The upgrade/downgrade page shows important details about the package (the description) they are upgrading from and too but there are no details for them to compare so they can make a better decision.
We are currently doing this with a hook but it would be nice if this was done by default.
