[Fedora-spins] change to spins template

[John Poelstra]

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 :)
