Add multi-line chat

README.md

 
 List the `users` you'd like to include in the chat, separated by commas.
 
+List `colors` for each user, using RGB hexadecimal codes (like #ff0000 for bright red). If a user isn't assigned a color, their text will be black (#000000).
+
 ### Usage
 
 `> python3 main.py`

config.ini

 logfile = chat.log
 sizew = 640
 sizeh = 480
-users = MyName, MyOtherName
+users = MyName, MyOtherName
+colors = #cc0000, #00cc00
