Prevent the great wall of text (force line breaks, punctuation)

[Alpha1]

Since migrating to xenforo we get a lot more mobile users. One of the downsides of this is that they often post large texts without line breaks or punctuation, which results in unreadable posts.

To solve this I suggest the following functionality:

• If a post has more than X characters and no line breaks, then show an error to the user that they must add line breaks, before the post can be submitted.
• If a post has more than X characters and no punctuation, then show an error to the user that they must add punctuation, before the post can be submitted.
