[Added] Savage Weald: Backwoods Brawl [Challenge]

[KovalTN]

Another zone to add so that POIs can be added/shared:

Savage Weald: Backwoods Brawl [Challenge]
exp17_dun_savage_weald_02

Map image/geometry has the same layout as Savage Weald overland zone map. In fact the game client calls that map currently (which I realize isn't necessarily indicative, but still). I verified the coords/zonerect this morning just to be sure.

Thanks!
