Fixes and Optimisations - EA Update v0.3.0.40

Happy weekend all, just a quick little update fixing a few bugs and improving performance. Not quite there with translations i'm working on, but thought an update was due as a few issues highlighted in last couple days.

• Improve: Droid job checking, reduce lookup freq (user and routine repairs).
  
• Improve: Routine repair checks, delay path lookups.
  
• Improve: Airlock internal o2 testing reduce lookup freq.
  
• Fix: Docking connectors not classified as external in some checks (could make floors internal and buildable on).
  
• Fix: Pirate target switching check target exists.
  
• Fix: Damage item process. Check target exists for leak storage, fx, fire and nearby damage checks.
