[Added & Tested]Duel arena

[Quido]

The countdown timer should play a sound when it goes down.
The duel arena isn't sealed off.
Maybe a few different locations which can be chosen when you want to duel someone.

I'll add the sound, to seal it off I'm waiting for Tenshi to give me the object and coords of the fence. Some different locations to choose from sounds good, maybe I'll add that in a future update (not really a priority for now). Maybe make a new topic for this suggestion, so we can suggest places and add coords there, and keep it for future reference when I get around to it.

First 2 things are now added, last suggestion is more of a long term one, so I'll close this topic for now.
