bootstrap angular on "document ready" instead of window.onload

Browse source 
- use jqLite api to bootstrap angular
- when jQuery is present DOMContentLoaded or hacks for IE are used
- when jqLite is present DOMContentLoaded is used for modern browsers
  and IE9 and window.onload is used for other browsers.
- test html for comparing DOMContentLoaded with window.onload
