[Spaceships] Powering smaller systems

[SCAR]

Actually, Power Points from Power Plants and for High-Energy (!) Systems scale 3 to 1 with SM.

A 1G Beam is a Major Battery (a single system) at SM+9, requiring 1 (SM+9) Power Point as a High-Energy System
3x 1G Beams would be a Medium Battery (a single system) at SM+10, requiring 1 (SM+10) Power Point.

We can therefore conclude that 1 Power Point at SM+10 is equivalent to 3 Power Points at SM+9.

The same SM+9 1G Beam would also be a single Smaller System in an SM+10 Hull, and would require 1 (SM+9) PP or 1/3 (SM+10) PP.

I see no problem having Power Plant power smaller systems on this 3-to-1 basis. You could also allow 3PP from smaller power plants to provide 1PP for a standard system if you wanted (although I'm not sure that would every really be worth it).
