Cleaned the TS TechTree #2

- Cleaned some Buildings by Creating Factory Templates
- created Civilian.yaml files which contains tge gaspot and lightpost
- By default in TS "not buildable units" are flagged with "owner: none"
because some units are only available  for campaign missions, they will
be uncommented when we have Icons for them :)
- The "WeedGuy" has now a sensefull name"
- The AI got some Defence Buildings... playtests are otherwise very
lonely :(
