Adding help by creating links to documentation webiste

Example :

- open a graph file
- github auth
- layout script
- ...

We need to create a new JSX component called `DocumentationHelp` which can be used across the application like that :
``

It should display as a html link with a help icon.
Design is not done

Start by locating the application's existing JSX components and the entry points where shared UI elements are defined. Use the DocumentationHelp usage in the issue as the interface to support, then verify that it renders the supplied title and URL as an HTML link with a help icon; the visual design still needs to be decided.
