City Map Update

Happy New Year everybody! We've added 2 new defense sites in the Black Ghost City. There are now 4 sites: park, center, dead-end, and nightclub. They are randomly selected when you load the map. Dead-end and nightclub sites are only available on normal and hard difficulty.

Here are the patch notes since the start of alpha 2 weeks ago:

1. City scene now has multiple defense sites: 2 on "easy", 4 on "normal" and "hard".
   
2. Vive headset with Valve Index controllers now automatically detected. The launch option "-platform index" not needed.
   
3. Added upgrading trap/tower sound fx.
   
4. Fixed WMR and Vive Cosmos flickering on initial load.
   
5. Lower back holster moved to chest holster making it easier for seated players.
   
6. Improved saber interaction. Damage based on speed. Head hits work now too.
   
7. Boat auto-pilot not engaging after using rudder and/or steering wheel
   
8. Updated tutorial graphic and text to reflect lower back holster moved to chest.
   
9. Laser pistol is now more accurate at point blank range however scope is more sensitive to hand movement.
