[Ogre] Correction- The First Factory State

[Mark and Rachael]

Oops, I caught a boo boo. There are probably others. 
The following line is incorrect: 

"The Combine player is therefore limited in purchase
of LGEVs to what was historically available: no more
than 2 supporting LGEVs per 3 normal GEVs purchased.
Thus,if the player chooses 10 GEVs, he can take a
maximum
of 4 LGEVs." 

It should read: "Thus, if the player chooses 10 GEVs,
he can take a maximum of 6 LGEVs."  But hopefully that
much was already obvious.
