First Marketing HOWTO (write a press release)

[Mel Chua]

While writing this week's FWN beat, I threw stuff from the recent CC 
press release discussion on a wikipage.

https://fedoraproject.org/wiki/Marketing_HOWTO_write_a_press_release

I figured this would be a good section to start as we accumulate more 
collective Knowledge of Marketing: 
https://fedoraproject.org/wiki/Marketing#Marketing_HOWTOs. (For an idea 
of what I'm hoping we'll end up with, see 
https://fedoraproject.org/wiki/Category:Infrastructure_SOPs.)
