Add two Israeli Government Owned Companies

I added Rafael Defense Industries, government owned arms manufacturer - http://en.wikipedia.org/wiki/Rafael_Advanced_Defense_Systems

And Moffet Institute, government owned teacher academy - https://en.wikipedia.org/wiki/Mofet_Institute

(cc @itvaru, please add them to your @israeledits bot!)
Changed to "Moffet Institute (Ministry of Education)" for sake of 120 characters. :)
