#6 Kill/reject all request that is not trade

[vitalogy]

The bot should cancel all request that is not a trade
request.

- Challenge (for duel) request

- Invitation to join a clan

- Global message sent by the WotC's staff [**put it at
low priority, because currently WotC send message only
when the server is going down for the weekly
maintenance]

- Private Message (i opened another thread for this,
since a code have been posted)

-Any other that I forgot?
