Update bot.js

/*MasterBot v1.2
 
Designed by Get52, Bruno02468 and Randomguy_
 
Notes:

- Use the run script on the GitHub repo please
- use "disabled = true;" to turn off the bot
- Changing your nick during usage may result in bot shutdown
- /me commands still need some work
 
Updates:

- This now samples continously
- Doesn't sample your own messages that's a good thing
- Does not read PM's and join/leave messages
- Speak and /me commands adapted
- Uses .ajax to send to server (did I do it right?)
- Objects are better than arrays for this
- Antispamming added
- Does not log its own commands
