`brew cleanup` cleans up the download-cache

Manpage updated.

The -s switch is "scrub" and removes downloads for uninstall formula which are downloads for the latest version of that formula still.

Please NOTE cache is NOT cleaned if a formula argument is provided. I couldn't be bothered. Patches welcome :)

Closes #2923.
