[UP-4274] OSX focus stealing

https://issues.jasig.org/browse/UP-4274
How feasible is it to accomplish not stealing focus on builds on OS X without introducing dependency on this "alpha" release artifact?  Relying on "alpha" stuff for building production software gives me the heebie jeebies.  If this thing is solid it should be available in a real release; if this thing isn't solid we shouldn't use it for building serious deploy-to-production software, right?
