Alpha 9 - new clouds

Hello Gardeners. I've posted a new build of Gravity Garden, Alpha 9.  Just a few changes since Alpha 8:

• New Cloud system. Clouds now drift about and occasionally clump together. When enough of them gather it will rain.  This will be xpanded on later with new types of 'rain' - including pests and other challenges for the player. 
• Tweaks to the zero-G locomotion. Still tweaking the various Speed settings for the free move locomotion. Really need some more testers for this. I'm pretty much immune to VR sickness so it's hard for me to judge what is too intense. :)
