Message:

Extract chats as structured data.

• add_chat_detection_format() — to add a chat regex pattern
• get_content_chat() — to grab a chat from content
• get_the_chat() — grab the chat from the current (or passed) post
• the_chat() — output the chat in formatted HTML
• paginate_content() — puts the <!--nextpage--> splitting stuff into a function
• get_paged_content() — grabs a page of raw content, needed to paginate chats properly

see #23625. props wonderboymusic, lancewillett.
