Ubufox should have integration to add repositorys and keys easily

When you go to a launchpad ppa it should be made as simple to add a repository as it is to install a package using apturl, they keys are the main annoyance as I find it hard to remember the correct syntax for apt-key "sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys", and saving the key to a text file then using apt-key or the gnome ui and then deleting the key is annoying.
