# Conflicts:
# erepublik/citizen.py
Citizen.set_default_weapon() - eRepublik should return list with all available weapon qualities, but when a battle is just launched, they return only dict with barehands
Citizen.fight() - no longer calls self.set_default_weapon()
Citizen.find_battle_and_fight() - now calls self.set_default_weapon() just before fighting
Citizen.update_war_info() - returns previous battle list if responses 'last_updated' isn't more than 30s old
New:
Citizen.get_battle_for_war(war_id) - returns Battle instance for specific war, if battle is active for given war
improved multi bomb deploy with auto traveling,
Citizen.fight() simplified battle data gathering logic -> Citizen.shoot logic improved
Citizen.all_battles are now defaultdict with default value of empty/invalid battle, for times when trying to do things with battle which is not in all_battle dict
The same medal kind (Maverick div BHs) can have different reward value - group them by kind-reward.
Citizen.post bugfix (with no data and json arguments) TODO: Must check where post is called without data or json
