Introduce wizard-like help system

[simboss]

We should introduce a wizard like help system taking extra care that it will work nicely on the mobile where it will be the default help system.

A few interesting examples:

1. http://www.geoportal.org/
2. google "Take a Tour" feaure

We could include the intro.js library (http://introjs.com/) in a new plugin to manage and control the steps

concept visualization:

• first start:

• using help button:

• steps:

Look also at this one: https://gilbarbara.github.io/react-joyride/

Yes, take a look at which better fits for us. They seem very similar, but the second seems already react-integrated and with more built in options. What do you think @allyoucanmap ?

I just finished to try react-joyride and i think it's better than introjs.
The steps and the main component are easy to stylize and modify rather than introjs. I think we should use 'react-joyride'.

Ok, let's move on with react-joyride
