Fight class already loaded.

The fight class is being loaded before the save and close button is pressed on the general settings page. And cannot be changed unless user starts and then stops the bot.

For example:

1. Click the General settings button. The settings window appears.
   
2. Select a fight class and press the settings button for the fight class.
   
3. Make your changes to the fight class.
   
4. Close the fight class settings window.
   

At this point the fight class is loaded. If the user wishes to open the settings window again, they are unable to. The only way to make further changes to the fight class is to start running the bot and immediately stop it.

I propose the fight class should not actually be loaded until the user presses Start.
