The position of the toolbar is now configurable, it can be specified on the caller's side. The possible values are top and bottom and the key for the setting is toolbarposition. Also extended the logging of the web view's load errors, it now logs the error code too, not just the localized description of the error that occured. Added the browserOptions to the init method's parameters in order to make it conveniently accessible from the ViewController.
Fixed the positioning and autoresizing for certain rotation scenarios. The autoresizing masks are applied conditonally based on the browserOptions.toolbarposition flag to ensure that the toolbar is in it's correct place.  Also added a utility function the query the necessary offset for the status bar: the function takes care of the iOS version and orientation caused differences without hardcoding the value as 20 pixels.
Fixed the 'barbar' typo for the property declaration of the new browser option: toolbarposition.
