STPopup may lose its reference to view controller, especially after memory warning, causing bad access crash. Checking for existence of view controller before removing observer prevents the crash

@artonragsdale _viewControllers in STPopupController holds strong reference of UIViewController, and it's not cleaned up when memory warning is received. Even it's set to nil, calling a function to nil will not crash. Do you have any crash log on this issue? |

@kevin0571 I actually fixed this a while ago and just got around to submitting a pull request but it did solve a crash bug my app was experiencing. I'll have to look back through old crash reports to see if I can find it. |
