Fixed localisation issue.

Changed drifting wreckage object in Vazuran Menace evet chain to be targetable by special project.

Ancient robots feature wasn't exchanged if they were immediatly hostile.

Fixed crash at the end of the surveyer quest chain.

Vazuran raids now add a custom deposit_blocker that is exactly the same as the standard d_bomb_crater with the only difference of it not having a deposit under it. The raid is meant to add a blocker not a deposit.

Prevented event deposits from being placed on random planets at game start. Needs a new game to take effect unfortunately.

Prevented crucible event from killing every last pop in the galaxy.
