Moral issue on "Missle Dance"

[Barnacle Bill]

Until a patch fixes this bug concerning the engines, it could be corrected via a mod. Basically, the only difference in I, II & III levels of a given engine is how much they cost. So, remove all the current engine components in favor of a new series just called "Engine", with level 1 providing no bonus points and each level II+ providing one more bonus movement point than the previous. Multiply the research cost of each level of Propulsion by 3, and eliminate the unused levels at the top. The AI should then handle increases in propulsion technology correctly, and it should work pretty close to the same as now for human players.
