Updates

Removes the massive disclaimer. Homebrew themselves merged in my 10.10
patch last week, and now tentatively support the OS itself. They
continue to not support patches that need to be accepted upstream,
which is a policy I support but I know people continue to rely on those
formula, even on DP/Beta systems. I reiterate these changes aren’t
meant to be long term. Upstream developers should be working to blend
these in as quickly as possible before Yosemite’s release.
