Updated Xcode command line tools installer script now available

A while back, I developed a script that will download and install the Xcode Command Line Tools on Macs running 10.7.x and higher.

Apple would sometimes have both the latest available Xcode Command Line Tools installer and the just-previous version available on Apple’s Software Update feed.
