I have put the modal element for the help directive directly in the index. Basically, we should avoid stuff like that. I did this because I didn't get it to work if I put it inside other elements (for instance, help in the print element inside the accordeon)...but this was probably just me not being good in css/html.

A probably better solution would be to put it inside the help template and the move it to the 'body' elment inside the directive link function. Would this be better?
