When optimizing a rocket for a planet like Eve the thrust and ISP of an engine have to be adjusted to higher atmospheric pressures than Kerbin (more than 1 atm), otherwise the tool might return rockets that wont be capable to take off there, or that have the wrong Dv needed.
So I implemented the methods to calculate ISP and thrust using the atmosphere curves that Unity uses with atm as the input parameter, and added the option to populate the atm value depending on the planet or edit it, in case the user is planning to take off from a mountain, or wants to find the optimum stage for a given altitude.
