Simple chat web app for Toledo Talk

"Chat" may be the incorrect term. I'll simply call it "talk."

Details:

* web-based app.
* text input field to enter message is located at the top of the site like a microblog and not at the bottom like in traditional chat or message apps. 
* post button next to text input field but hitting the return key will also submit message.
* messages are displayed in reverse order, which is youngest to oldest.
* for now, zero formatting in the messages. even raw urls won't be transformed into a clickable link.
* limit message size to 200 to 300 characters.
* display message as a paragraph block.
* the client-side javascript will poll the server every 15 to 30 seconds.
* display the most recent 50 or so messages.
* for each message block, show:
** author name
** message text
** created date
* database table fields
** message_id - auto increment
** message_text
** author_name
** author_id
** created_date
** status
** ip_address
* no joins
* select ... order by id desc limit 50
* server-side script returns only a blob of json that the client-side javascript parses for browser display.
* display the page without the normal ToledoTalk.com header or nav bar.
* the messages will display at the default normal width of Toledo Talk's content. 
* responsive design:
** adjust the text input field length accordingly.
** adjust the font size of the messages.
