We should add an option to specify what pages a gadget is active on. Many probably just do this manually, but it looks reasonable as some gadgets would only be useful for contributors' talk pages for example. This could be a namespace name, or sometimes even a glob mask (Wikipedia talk:Articles for Creation/*).
