Lift and drag are not correct in internal evaluators.

[KlyithSA]

The fallback evaluators for lift, drag, and terminal velocity used when FAR is not installed are wildly incorrect. I noticed that they cite NathalKell's AeroGUI as the source, but made a small error when porting the code such that lift modules would never be checked. (The if !p.hasLiftModule block was not closed, so the loop to evaluate lift modules only happens in parts that don't have lift modules.)

Made PR #153 to fix this.

I can only assume that nobody has noticed this for years because everyone who cares about lift and drag numbers uses FAR. :)
