Vostok/Voskhod Overhaul

A more limited overhaul, due to lack of good sources. Changes include:

Vostok, Voskhod, and Zenit mass brought into line when loaded with the correct crew, cargo, resources, and equipment
Vostok, Voskhod, and Zenit now use SM-II tankage instead of massless SM tankage
Vostok, Voskhod, and Zenit ablator levels increased to better survive worst-case reentry profile (from natural decay and/or backup SRM)
Vostok, Voskhod, and Zenit battery capacity increased to probably historical levels
Voskhod has been given a landing braking motor to allow for safer landings
Vostok Service Module now uses SM-II tankage instead of massless SM tankage
Vostok Service Module now has Gas Generator biprop RCS
Vostok Service Module cold gas RCS thrust reduced to real values
TDU-1/S5.4 reduced to one ignition only
