Brought back Excon for package downloading as the method recommended by async-http is unreliable, added support for importing games, repairer and updater tasks are both now simple subclasses of installer, implemented verify_files for checking installed files to prune download package list (currently causes Api.package_details to fail..., so disabled for now), misc. changes.
