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.
I know it's not officially supported, but we are installing OSC servers on Debian Wheezy platforms with no apparent problems. In fact, we use your [chef-server cookbook](https://github.com/opscode-cookbooks/chef-server).
