Implemented checking if somebody has messages and flushing them.

syntax is "bot.trigger tell me about <nick>" and
"bot.trigger tell <nick> nothing"

THE BEST SYNTAXES EVER CLEARLY AND NOT BAD AT ALL
Removed useless debug print()
Added checking who has messages and a message if nobody has any.

syntax "bot.trigger tell me about everybody"

"tell me about" will automatically blap you if nobody has any.
