Added special plans for unorthodox origins (ringworld/void dweller), their AI still should be improved, but it no longer autocollapses (I am temporarily using economy plan for them).

Fixed reported tech bug, tweaked galaxy spawn (I went overboard with merchant guilds spawnrate causing everybody to be one).

Fixed missing branch office building and missing opinion modifiers.

Updated the mod to work with 2.6.*

Small changes of the building weights (to make sure AI doesn't upgrade labs/foundries/factoris if there are too many open slots).
