Generic spin page template created

[Mel Chua]

Because I couldn't find one: I made a generic spin page template based 
on the KDE spin page. 
http://mchua.fedorapeople.org/spins/spin_page_template.html

I've linked to it with some usage instructions on 
https://fedoraproject.org/wiki/Spin_webpage_creation_SOP#Download_the_HTML_template. 
Patches extremely welcome; I'm not sure if I did a great job of making 
this generic, but I'm sure I'll find out momentarily while making the 
other spin pages. ;)

This should probably be hosted somewhere outside my fp.o space if it's 
useful; suggestions on where to put it in the web repo welcome, I'm 
happy to make the push to wherever.
