CC license changeover complete

[Ian Weller]

The Docs team has finished converting all current documentation and
project content from the OPL to a CC BY-SA 3.0 Unported license.

Additional information can be found at:

Thanks again to Tom "spot" Callaway, Richard Fontana of Red Hat Legal
and all the Fedora contributors who helped with the conversion. Here's
to freer documentation for Fedora 12!
