Added free-for-all mode for fight event, two new values on the gamefile:
- "free-for-all: false"
If true, will enable free-for-all mode. In that case, the entrance location will be used to teleport the players instead of entrance1 and entrance2.
- "free-for-all-delay: 15"
Delay for players to spread across the arena before the pvp is enabled after they are teleported to the entrance location.
