Hard-code the application URL

Hard-code the URL for your GWC hybrid mode application for iOS.

To hard-code the application URL, update the values in ghc-ios/ghcAppDelegate.m:

 // Set the application defaults
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSDictionary *appURL = [NSDictionary
 dictionaryWithObject:@"http://127.0.0.1:6394/wa/r/gwcdemo?OutputMap=DUA_HTML5"
 forKey:@"app_url"];
