center of mass, center of thrust, and center of pressure should scale with the crafts size

[dogthehog]

As you can see here when designing a small craft or probe its impossible to tell if your winglets, thrusters or little gadgets are aligned properly. The size of these markers should scale with the size of the craft or part cause tbh they seem too big sometimes even when working with big rockets (IMO). If people don't like that maybe make the scaling of these markers a bar in the settings window?
