Item description with markdown

As a project manager from a software development company I would love to have the ability to add descriptions to specific items/tasks (different to updates, since it should be a content easily seen at top I guess). This would help creating specific tasks with complex explanations, images, etc. I don’t think HTML is necessary, but markdown is a very friendly language to write documentation.

If we get to add this plus code linters we are at the other side.
