Add segue subclass that presents without animation

Sometimes I want to perform the segue (and present the modal view) without the animation. This is useful if, for example, you are presenting the modal when the app first launches.

I don't know of an easy way to pass parameters or configuration options to a segue, so I simply created a new segue type, DATBlurSegueWithoutAnimation, that inherits from DATBlurSegue but overrides the animation code to do nothing.

I don't know if this is the best way to do it; I'm open to alternatives.
