Update bot.js PUSH

Updates:

- "undefined" submit error fixed
- kek @ toggle wasn't even implemented, reverseVars() "disassembled"
- I am removing the "waiting" period altogether as the bot will still function. Since you are branching it out I feel it's bothersome and no longer necessary.
-I had to remove a line b/c people on the chat will ban you for anything from emoticons to threatening to ban them, no offense intended.
- Other edits: !masters function, !roll to !checkem (this is what the regulars call it), removed unnecessary brackets (learned about it in class today) 

I see you have updated since I started editing. I carried over everything you changed EXCEPT:

- Keeping cutoff at 175 characters, it is plenty
- Adding periods to Heads and Tails

In the next update I will try and condense the code down :)
