Important content and general tips have reversed classes #2527

Bug Report

Steps to reproduce

Create !> **Time** is money, my friend! and ?> _TODO_ unit test

Current behaviour

The !> is produce an element with class tip, meanwhile the ?> is produce an element with class warn (Which stands warning). I think the class is mixed up because the style doesn't follow the meaning of the class.

<p class="tip">	<p class="warn">

Expected behaviour

Use more appropriate and clear classes for each callout. Using the .tip and .warn classes might still make sense after being reversed.
