Add iPhone 5 support

Hi there,

So I read this article: http://stackoverflow.com/questions/12395200/how-to-develop-or-migrate-apps-for-iphone-5-screen-resolution

And all I did was add a 1136 x 640 "launch image" and it seems to work on the iPhone 5 taller screen now.  Not my finest work, but this would be my very first contribution to any iOS project ever!

The funny thing is that my first Blackberry Playbook contribution was porting PasswordMaker to that device :)

Hope this goes smoothly, will be crossing my fingers!
