My compile & run cycle just went from (and I counted) 11 seconds to ~1 second.

What is happening?

Injection: Dynamically re-compiles files you've saved, and ships those changes to your currently running app.

How does this work? In simple, it is an Xcode plugin that can compile your code into a bundle, this bundle is then added to your app. It will include newer versions of the classes you've injected via this bundle, then it is up to you to do something with this.

What does this PR do? So, the default behaviour of Injection is to allows re-compiled classes to know that they have been re-compiled. Given the viewDidLoad heavy view controllers we create I felt it would be better for our flow to work a little different from that.

Instead of letting the view controllers themselves act upon the injection, our top view controller is expanded to deal with the changes and adds some smart defaults. I've been recommending everyone use our developer extras to do their app cycle work: e,g,

- (void)runDeveloperExtras
    LiveAuctionViewController *liveVC = [[LiveAuctionViewController alloc] init];
    [self pushViewController:liveVC animated:YES];

I've expanded that to include a pop when injected, and to re-run the code inside developer extras. This means that the code inside runDeveloperExtras will be run on every injection. So you can keep working in the same file, constantly injecting new versions in again & again.

This Danger fail is totally legit, however, I am very purposely editing this file. So we can consider it green.
