Created a fix that would cause an assertion on the TextField in the circumstance that the UserDefaults returns an empty string.
Added an option of loading the IPA from the file menu versus drag and drop.
Also fixed a bug where if the NSUserDefaults output path had spaces, it would not properly convert to a NSURL.
Further purged unnecessary menu items and cleaned up some of the text.
Updated the readme file to include some of the progress that was made
