MIFOSX-1583 - Clarify Help Menu

I tried to improve it and this it what I did:
How it works?
'Help' now is based on simple JS script recognizing actual URL, actual context and choosing best user manual document/topic about it.
You can watch how it works here: https://www.youtube.com/watch?v=KwBulv5aKzs&feature=youtu.be
What do you think about this solution? Could it be? In JS I'm beginner but I got good lesson of JS-coding when I was doing it. :)
Best regards

Helpf() function moved to MainController

Help script moved to MainController.js
