Platform support policy proposal

There is a fair amount of confusion about the specific operating system platforms, platform versions, etc. that Chef Software, Inc. supports for its products. This RFC will clarify this by calling out the individual operating systems and their releases as explicitly supported or not.
Re: OpenIndiana - I don't think it's used by many people, but my familiarity has been mostly with OmniOS (for somewhat obvious reasons). If the level of effort is small (and it sounds like it is), we should support both OmniOS and SmartOS.
