This patch adds a ArchiveDownloadStrategy that handles downloading tarbarlls and decompressing them into the staging area ready for brewing. Refactored safe_system and curl into utils.rb Signed-off-by: Max Howell <max@methylblue.com> Modifications to Adam's original patch: I reverted objectification of checksum verification because I couldn't think of any other download validation methods that might be useful to us in the future, so allowing such flexibility had no advantages. If we ever need this to be OO we can add it. But for now less complexity is preferable. I removed the @svnurl class member. Instead download_strategy is autodetected by examining the url. The user can override the download_strategy in case this fails. Thus we already can easily add support for clones of git repositories.
