Patch notes!

We've had some limited feedback and a number of small level bugs, as well as some feature requests.

• Added sub-renderer flags for editing vs simulating for slightly better performance
  
• Tweaked a number of audio sources for a better balance
  
• Clamped Camera height to +- 8m, as some cameras were escaping!
  
• Did a performance pass low-end machines, removing a bunch of physics objects and detail that was on there for 'show' - if you have an area that's not doing well, let me know!
  
• Reduced quality of HBAO and Motion Blur on lower detail settings to improve performance.
  
• Improved feedback on Thrusters for usage, Fuel, etc.
  
• Improved focus on UI elements hiding when not needed
  
• Added Volume settings under the Settings menu
  
• Added a basic tutorial that is displayed upon entering the Editor on Basic Diagnostics 1
  
• Allowed skipping of intro camera on more keys and buttons
  
• Added mostly-complete pad support. Should be finalised for Patch #2
  
• Fixed a few collision issues with camera and players falling out of the world.
