Change licence to MIT and use your email

Updates the licence to use a proper licence without swears so we can use it in a public-facing app.

Looks like you copied and pasted the example licence off the DWTFYW licence website. I've updated the licence with your name and email.

This is a really great project and totally fills a hole left in XCode's current feature set but because we use Cocoapods to auto-generate an acknowledgements file, we end up with swears in a publicly facing page. I want to give credit for your work (obviously)! Using the MIT licence doesn't change anything, it's still totally permissive and means that you're not liable for anything. 

Also, I imagine apple doesn't look too fondly on 4+ age rated apps with swear words. Admittedly, it's not easy to find, but Apple are sticklers for detail.

Cheers
