Pre-warp Techs

[out_law]

Here an idea, why not start a game with no warp at all, so idealy every one is non-warp races, later as you get more tech way not add ship which has the abilty to make warp points, I'm talking about in adding a new abilty to vehicles in vehicles.txt file i.e. :
Number of Abilities := 2
Ability 1 Type := Combat To Hit Defense Minus
Ability 1 Descr := Large size makes base 40% easier to hit in combat.
Ability 1 Val 1 := 40
Ability 1 Val 2 := 0
Ability 2 Type := Open Warp Point Distance
Ability 2 Descr := Opens a wrap to a anthor systemt.
Ability 2 Val 1 := 10
Ability 2 Val 2 := 0

The only problem is the ship can carry on making warp it not like a warp opener comp. It's a shame that warp will always be open and will not close on it's own, any way just an idea.
