Shifted the initial HomeVC population to a background thread to avoid blocking launch processing Added some logging for database 'ABORT' errors to better identify cases of deadlocks Added a launch timeout modal to allow users to share their logs if the startup process happens to hang Updated the notification handling (and cancelling) so it could run on background threads (seemed to take up a decent chunk of main thread time) Fixed an issue where the IP2Country population was running sync which could cause a hang on startup Fixed an issue where the code checking if the UIPasteBoard contained an image was explicitly advised against by the documentation (caused some reported hangs) Fixed a hang which could be caused by a redundant function when the ImagePickerController appeared
