Star Explorers Testing Branch Updated to Pre-Release Version 0.1.5

Lot's of small fixes in this one.

[h3]Alien City:[/h3]

• I had to change which planet the alien city appears on due to the temperature being too high for liquid ammonia. At first I tried manually adjusting the temperature, but this did not work properly after reloading the game somehow. So I set the temperature like other planets , via star temp and distance from star
  
• If you already started a new game, the city will not be in the same location, but two planets further out. This may cause issues, and the city may be inaccessible if that planet is a gas giant. It should work properly for any new games though
  
• Next step will be to update the alien city model (from the outside) so it looks better
  

[h3]Aliens and Floaters:[/h3]

• Fixed issue where aliens were stuck up in the air after landing on a planet
  
• Furry aliens (also those with crystals or fungus) had a negative impact in frame-rate. This has been improved.
  
• Frame rate in caves with "floaters" - those eyeball like aliens - has been improved dramatically. Somehow it was creating way too many of them
  
• Fixed a problem where tree leaves were appearing without alpha - like big black squares.
  
• Fixed issue where floater explosion sounds were getting cut off early
  
• Fixed issue where floaters were not respawning after returning to a planet
  

[h3]Ancient Ruins:[/h3]

• Improved debris scattering on ancient ruins
  
• Stair colliders have been added to ancient ruins (inside and outside) so you should not experience as much jerky movement when going up
