Defination and Purpose of 'GlobalButtonOrderGenerator'

[dnqbob]

Orignal GlobalButtonOrderGenerator is very strict and only enough for classical C&C global order button and even only inherited by two classes (powedown and sell) at present, because repair function is more complicated after it can repair vehicle which is out of the box of GlobalButtonOrderGenerator.

I feel bad about it, so what is Global Order stand for in OpenRA?

IMO, Global Order should be defined as "let actors perform regular action while ignoring current selection collection set", a very special design can be seen in most C&Cs, and all designs that are similar to this defination or purpose can&should inherit this GlobalButtonOrderGenerator.

I am not going to put this in tag of bug because it is functionally correct, but not very fitting in logic in code.

Should we rewrite the GlobalButtonOrderGenerator and it's derived classes?
