All class option on config read

[cazaman11]

More of a feature than a bug imo. When first opening the app, you're unable to modify the weapon and crosshair dropdowns and required to select a class. however if you click the read config button it will make those dropdowns selectable allowing you to apply to all classes if you dont select a class.

I think it'd be best to keep this feature but have it more accessable with either a clearing the class option or an all class option.
