v0.2.0.9 - Pirate addition

Now have pirates that will make attacks on you space station! How frequent is based on difficulty, defenses, if your trading beacon is on and if a trader is nearby. Shields are now more useful as will reduce incoming laser damage.

Also have a new scrap/debris space item to watch out for. These are generated via destroyed ships. Scrap  can now be grabbed by tractor beams and placed in salvage depots. Scrap recycler will then process scrap into metal, much like the mining laser and captured meteoroids into ore.

Lots of bug fixes and improvements as well, it's been a month since i've updated the demo.
