Sound FX Update - v0.8.0.21

With this update i've added sound effects to items that have been missing them. At the moment that is the bar, canteen, fuel cell, life support, green house and co2 scrubber. There are still some more to add, but i thought i'd get this out, as i've made numerous fixes with the sound code. Audio positioning should now be working correctly, item sound location should be centered correctly and when pausing and unpausing some sounds weren't restarting.

There may still be some adjustments needed so let me know if something sounds odd. I'll be doing some more testing over next few days and also including more sfx for items that are still missing them. So expect another update after that.

Few other little fixes as well, mainly with pathing.

• Canteen and bar sound added when in use (>1 person).
  
• Greenhouse light buzz added.
  
• Life Support and CO2Scrubber fan sounds added.

• Fix: Don't attempt to haul any dead if no outside access.
  
• Fix: On emergency, cancelling another job requires reset path end on item.
  
• Fix: Hauling dead should not update item path grid like other hauling.
