Installed Packages don't show up in UpdateInstallationWizard after they're installed

[SaintSkeeta]

It would be nice for the packages installed in the Sitecore Package Deployer to show up in the list of previously installed packages in the Updated Installation Wizard.
I can see that this list is being read from the "/sitecore/admin/packages" folder....so maybe the Package Deployer could also copy the package there once it's installed, so it's easy to see what packages have been installed previously (or may need to be re-deployed).
