SFX and Web version fixes - patch 0.0.6

Hi,

I just threw up version 0.0.6. This fixes NPC traffic in the web version (which may solve other web issues hopefully). As well as adding sound fx.

• NPC traffic has been reworked. Should now work on the web version
  • NPC traffic now should also make a doppler whoosh sound as they fly past you
  • NPC traffic audio stream player is dynamically loaded and unloaded as the traffic comes within 100 meters of the player
• Modified the player's ship engine noise
• Added a low drone sound on a loop.
• I removed a large amount of errors in the editor.
• Some safeguarding was added to the editor to mark player input as handled.
• All models are now exported rather than using .blend files

I now have our version control sorted for collaboration and will have new assets and models incoming soon! (It looks much better than my garbage)
