New Pirate Behaviour - v0.7.0.46

Pirates now have a strafe attack, so rather than targeting a specific item, they will fire continually whilst moving over your station. Pirates previously would also always try and board, and grab any scrap in their path, i've now made that a possibility. These changes make pirates a lot more interesting, and dangerous, as they are likely to cause more damage. I may need to balance this further so if you find them to strong do let me know. Oh and do have a new pirate ship graphic for a bit more variety.

Patch notes:-

• Pirates have a new strafe attack, damaging tiles/items along their path.
  
• Pirate scrap collect, dock, and target/strafe attack now set randomly.
  
• Fires no longer spread if they are being actively put out.
  
• Spread fire chance takes into account co2 levels.
  
• Fix: "No asteroid selected for mining" message could appear if mining droid not assigned due to no storage.
