ionRadio fix for iOS 9 bugs

ionRadio.js

/**
 * ionRadioFix - fixes a bug in iOS 9 UIWebView that breaks the tilde selector in CSS. To
 * use this fix, include it after your Ionic bundle JS.
 * 
 * Note: due to Angular directive override limitations, you'll need to change any reference
 * to <ion-radio> to <ion-radio-fix> to apply this patched radio button.
 * 
 * Also, make sure to add the new CSS from the second part of this gist.

Thank you for this patch. Is it still needed now that 1.1.1 is out ?
