[Fedora-spins] change to spins template

Just looking here and reviewing the spins waiting for review and I've noticed that we don't call out the release the spin is targeted for. https://fedoraproject.org/wiki/Spins_New_Spin_Page_Template I think we we should add the targeted release to the template. In addition, for simplicity sake and permanent URL reference we should also create a new feature page for each major Fedora release, instead of constantly rolling the pages forward. Looking at this particular page I can't really tell what release a spin owner is targeting. https://fedoraproject.org/wiki/AOS_Spin the suggested ISO names contain Fedora-10 which would seem odd if it is for the Fedora 11 release, but yet I can't tell :) John
