Title: Drop support for Snow Leopard

* Snow Leopard was released in August, 2009 (about four years ago).
* Yosemite will be released in a couple of months.
* We support the last three versions of Ubuntu, so this is a little more
consistent.
* Use the same format as the Linux "Requirements" section for consistency.
