Thanks for the pull request.

Unfortunately, allowUniversalAccessFromFileURLs is considered private API by Apple, and has been actively discouraged by WebKit developers due to potential for breaking in future iOS versions. Cordova will not adopt this because it introduces too much risk to apps built with Cordova.
