Created the basis for the chat room.
Based on Chris Coyier's app at http://css-tricks.com/jquery-php-chat/
Mostly borrowing code to learn about Jquery.
Made the author/channel fields non-null
Added endorsement and dismissal to the chat.
Merged the chatroom into the world map and lesson pages.
Also took the jquery and bootstrap dependencies out of the overwritten script block.
Finished most of the testing stuff for the chatroom.
