Enable help text in separate window.

The help text from index.html is copied into an own html File and linked
with from the "Code" section. This enables the user to right-click ->
"Open in Separate Window".

As I am not familiar with jQuery and angular.js, I tried the simple way I could find which is not optimal as the help text copied to a different location. Unfortunately googling didn't find me a solution within the angular.js framework. Any better suggestion would be welcome.
