Tweaks to fix more LLVM warnings

…f the delegate was removed before we called it.

(The cache only stores 200 response codes.)

The client can still check if the cache was used or not by checking 'didUseCachedResponse'.

It is not safe to call retain on these objects unless we're on the main thread, as the main thread could have already started a dealloc() (but not reached the setDelegete:nil call) on the object when retain is called, potentially resulting in an object that is both retained and dealloced.

The previous mechanism can end up calling a delegate that has been removed by a setDelegate:nil, and hence may already be deallocated.

Now we run a callback on the mainthread, which only dereferences the delegate/queue and selectors to be called when it runs on the main thread.

The authenticationdelegate code is still using the old method. This should be looked at separately; it is slightly more complex as it needs to know if a delegate exists to be called.

Dismiss auth dialog

Import UIKit in ASIAuthenticationDialog
Add new reachability class
Tweak license to mention new reachability class

* Tweak cancel stress test to make it more likely to catch above issue
* Use an empty CFRunLoopSource instead of a timer to keep request thread runloop from exiting
* Only run the version numbering script if git is available at the path the script expects
* Tweaks

Stop dismissing dialog from request - doesn't make sense because the request doesn't own it

Add new isNetworkInUse class method that works on Mac too
