Add Multi-Size Text

It would be amazing if we could have multi-size text, like standard markdown. This is useful for channel dividers and static channels where content doesn't change much (Roles, Announcements, etc). This means that we won't have to upload images (reducing server load [yay]) and gets rid of the information around an image file with the name and file size on mobile. It could be a permission thing so that only roles with that permission can send certain sized texts. It would be very helpful and solve a lot a problems.

Thanks,
