AngularJS postMessage API

Allow angularJS to listen and publish cross-document messages though window.postMessage API.

Cross-document messaging is compatible with the following browsers as seen on Can I Use:

Internet Explorer 8+
Firefox 3+
Chrome 4+
Safari 4+
Opera 9.5+
iOS Safari 3.2+
Opera Mini 5+
Android Browser 2.1+
Blackberry Browser 7+
Opera Moble 10+
Chrome for Android 30+
Firefox for Android 25+
Internet Exploer Mobile 10+

Partial support in IE8-9 refers to only working in frames/iframes (not other tabs/windows). Also in IE 9 and below an object cannot be sent using postMessage. Partial support in IE10 refers to limitations in certain conditions

Tested on AngularJS versions 1.2, 1.3 and 1.4 in Chrome, Firefox, Opera, and IE9+.

IE8 is not officially supported by AngularJS
