Guild War system issues on OTX 2.x

[lucasoares]

Hello.

There are a few issues with the current war system in the latest OTX 2.x:

• On surrenders the guild balance are not updated (guild payment is lost by both guilds)
• On wars with fixed end date, the payment is also lost (should go to the guild with more frags or in case of draw, idk, maybe should go to the defender guild because it was challenged in the first place.
• After accepting war invite in a external war management (website), the logic to start the war in IOGuild::checkWars is wrong. It is re-using the war object and then it will set wrong value for the addEnemy method. In the end, if players are already logged in when the war was started, the first frag would go to the wrong guild.
