Testing Branch Updated to 5.0 Pre-Release Version 0.1.4

This is the second of a series of small updates primarily addressing the Alien City.

• I made sure the planet on which you will find the city will have Ammonia in the liquid state - it had the potential to be in vaporous form previously, and this was not what I had in mind.
  
• Now the pink fog should only appear if you go under the ammonia canal.
  
• Rain has been limited, so it will not appear in the city. In the future I may allow for rain, if I can find a way from preventing it appearing in buildings, but until then, I am just not having it appear on the planet.
  
• More NPC dialogue options! NPCs in the mothership and the alien city will have more to say.
  
• Removal of repeat statements. NPCs should no longer repeat the same phrase more than once. If you are loading an old game, they may still repeat themselves, but for new games this will not happen.
  
• Star particle effects had a problem where they got stuck in the middle of the star. This should no longer happen.
