Add a loadAngular function

    If something is added to the DOM with external tools, angular is not
aware of these changes (Ajax call, pure js DOM manipulation, etc...).
This patch add an utility function which will load angular on the given
element.
    There is also an example on modal, angular is now loaded when a
modal is shown.
