Just a simple mod to design civilian ships, there are also auxiliary slots and new components for civilian ships.

Colony Ship & Transport: 3x Auxiliary slots
Science Ship & Constructor: 2x Auxiliary slots

Civilian Ship Components:

+ Improved speed algorithm I -> Unlocked by Engineering I
+ Improved speed algorithm II -> Unlocked by Engineering II
+ Improved speed algorithm III -> Unlocked by Engineering III
(Make them Faster)

Science Ship Components:
+ Improved anomaly detection I -> Unlocked by space science I
+ Improved anomaly detection II -> Unlocked by space science II
+ Improved anomaly detection III -> Unlocked by space science III
(Less failing risk, more anomalies, faster anomalies research)

+ Improved exploration computer I -> Unlocked by automated exploration
+ Improved exploration computer II -> Unlocked by automated exploration + space science II
+ Improved exploration computer III -> Unlocked by automated exploration + space science III
(faster exploration)

+ Archaelogical Support System -> Unlocked by Archeology Lab
(faster archaelogy)

*Higher tier components will be add
