@tdipisa if we add a layer in gs-stable this would be easier for the tester

From our meeting with @MV88 to provide this functionality, I suggested to use the current image tool, improving it at least, instead of introducing the support to markdown inside wyiswyg that may be a problem for future maintainance of the functionality.
I love markdown and if we are going to introduce it I should do it as a complete alternative syntax.
I'd like to see with you too @allyoucanmap to have your opinion, next week.

• Please remove the mixed markdown support and so the new image tool. Use the image tool present in react wysiwyg (replacing react quill)
• Check for backward compatibility with existing templates created with react quill ( I tried and it seems to work on demo map)
