Title: Fixed 'flush' alias to work with OSX 10.7 & 10.8

The 'flush' alias is out-of-date. Starting in OS X Lion (10.7), it is necessary not only to use the old `dscacheutil -flushcache`, but also to use `killall -HUP mDNSResponder`. Apple explains this change in [this support article](http://support.apple.com/kb/HT5343). This change applies to Mountain Lion (10.8) as well as Lion.
