mob targets a player or entity in battle.

(Since config version updated, older config will be moved and the new
config will take its place.)

Fix config format for Entities.
Add feature to freeze combatants when battle starts, option to enable in
config.
BattleGui now displays health of all combatants.
Players can leave battle by entering creative mode (set by server).
Added battle size limit (default 8) can be set in config.
