Hello, fmuellner

This is a fairly minor problem, but the package metadata for the following packages are out-of-date.

* gnome-classic-session
* gnome-shell-extension-alternate-tab
* gnome-shell-extension-apps-menu
* gnome-shell-extension-auto-move-windows
* gnome-shell-extension-common
* gnome-shell-extension-drive-menu
* gnome-shell-extension-launch-new-instance
* gnome-shell-extension-native-window-placement
* gnome-shell-extension-places-menu
* gnome-shell-extension-screenshot-window-sizer
* gnome-shell-extension-user-theme
* gnome-shell-extension-window-list
* gnome-shell-extension-windowsNavigator
* gnome-shell-extension-workspace-indicator

They currently list the projects' URL as

  https://live.gnome.org/GnomeShell/Extensions

but GNOME no longer uses the "live" subdomain; requests now get redirected to the wiki. I believe the new URL should be

  https://wiki.gnome.org/Projects/GnomeShell/Extensions

(I'm filing this same bug report for multiple packages, so I apologize if you see this issue twice.)
