Large refactor to Formula, mostly improving reliability and error handling but also layout and readability. General improvements so testing can be more complete. Patches are automatically downloaded and applied for Formula that return a list of urls from Formula::patches. Split out the brew command logic to facilitate testing. Facility from Adam Vandenberg to allow selective cleaning of files, added because Python doesn't work when stripped.
