Unable to load local files with XHR on iOS

[NonSpicyBurrito]

I'm unable to load local files (file://...) with XMLHttpRequest in JS, to files in either Application.persistentDataPath or Application.temporaryCachePath. The same code works fine on Android.

It seems that the solution is to add allowFileAccessFromFileURLs and allowUniversalAccessFromFileURLs to configuration preferences.

I introduced UNITYWEBVIEW_IOS_ALLOW_FILE_URLS in #788 for enabling allowFileAccessFromFileURLs and allowUniversalAccessFromFileURLs, and updated binaries. You can enable these settings by defining UNITYWEBVIEW_IOS_ALLOW_FILE_URLS. Please note, however, that these are private APIs so the app enabling them may be rejected.

Thank you for the swift work.
