Don't recurse into UIDatePickers when searching for accessibility elements.
Fall back to the keyWindow's firstResponder if using KIFTypist fails and fallbackView is nil.
Wait for up to a second for the UI to catch up instead of immediately failing after a tenth of a second.
This fixes some random failures on slower test machines.
Use KIFTestWaitCondition inside runBlock: so that the failure actually occurs.
Use an NSSet instead of NSArray in classesToSkipAccessibilitySearchRecursion.
