Few More Fixes - EA Update v0.4.0.28

Making some good progress on adding some trader variety (will update work in progress shortly), but have noticed a couple bugs that cause game crashes whilst working on this. We don't want that, so little update with those fixes!

• Fix: Trader no longer used landing ramp animation, when docking at an airlock.
  
• Fix: Repairing ship, might not have correct type on selection, giving wrong type to cost calculation.
  
• Fix: Structure update on delete, may not have type after instance deletion.
