Electrical balancing

Since most spacecraft will have modules that consume a realistic amount of power, update batteries, generators, and solar panels to supply and store realistic amounts of power.

• One unit of ElectricCharge represents one kilojoule. A one-kilowatt load should draw one EC per second.

• In Realism Overhaul, the energy density of battery parts is in the range of 250 to 270 kJ/kg.

• RealFuels tanks can hold 346 kJ/kg at a volume density of 1 MJ/liter.

• Solar panel performance ranges from 0.063 kW/square meter in 1958 to 0.301 kw/m^2 in modern tech.

• The Squad 1x6 or 2x3 solar panels, used at their original scale, provide 0.96 m^2 of solar cells.

• The Mercury capsule carried 13,500 Wh of batteries (48,600 kJ). A three-orbit flight used about half of the available power. https://github.com/KSP-RO/RealismOverhaul/blob/master/Notes/Part%20Notes/Mercury%20Capsule.txt

As a first step on batteries, added a catch-all patch that multiplies all EC capacities by 12.5. This brings the stock Z-100 into the targeted density range at 250 kJ/kg.
