Support html in the tutorial steps

[offtherailz]

We should support to add html to the tutorial steps, to allow adding images, titles and so on.
This is already available editing the preset.
This should be supported :

• in rowStep, for customization
• we need support for i18n for HTML

The target is to provide a fully customizable and internationalizable tutorial

I just tested the current version of the tutorial plugin and we can add react component or dom elements in the title and text attributes in the preset files.

...
{
  title: (<Panel header={'bootstrap panel'}>{'panel content'}</Panel>),
  text: '<img width="100%" src="http://path/img/logo.png"/>',
  selector: '#drawer-menu-button'
},
...
