Ship Improvements - EA Update v0.5.0.18

Hi folks!

First update for the new year and i've made a few improvements to pirate ships (and traders).

I've decided that ships wont collide with scrap and meteors, just to simplify things. Think it makes sense that small ships would avoid these objects, much like the mining droid and workers when outside station.

Ships now if destroyed also have a chance of becoming a derelict, thereby giving more scrap resources.

Full patch notes:-

• Improve: Ships no longer collide with scrap/meteors.
  
• Improve: Destroyed ships have chance of becoming derelict.
  
• Improve: Derelict gfx updated to include newer trader ships sprites.
  
• Fix: Unneeded helmet sprite data in save data, remove.
  
• Fix: Smooth pirate deceleration when closing on target.
