Ron 790480c8da Removes all \red and \blue's (#2309) 
Removes all \red's and \blues in favor of span classes. \red things that were bold were replaced with danger because it's warning but bold.

/*
Defines a firing mode for a gun.
A firemode is created from a list of fire mode settings. Each setting modifies the value of the gun var with the same name.
If the fire mode value for a setting is null, it will be replaced with the initial value of that gun's variable when the firemode is created.
Obviously not compatible with variables that take a null value. If a setting is not present, then the corresponding var will not be modified.
