v0.0.0.100 - Big damage update (part 2)

Fa-Fa-Fa-Fire! Panic stations!  Things can now go drastically wrong on your space station now!

• Damaged fuel/air storage, now leaks into your station. So there are now fuel spills.
• We have fire! If things are badly damaged, they have a chance of creating fire. Much worse if there are fuel leaks! Now it might be useful to vent your station if there is a fire situation. Items are also destroyed if badly damaged!
• Droids now have an emergency job type, which coves firefighting/clear fuel spills, and repairing themselves.
• Yes droids now take damage (fires and being outside the station). They can repair at droid maintenance.
• Have added wear to production items, keep an eye on damage levels!
• Air Efficiency. There now is a point in having life support. Droids now move quicker in the ship if you have an atmosphere (and slower in space). Refinery also functions more efficiency. Only just started on this, but next update will see plenty more bonuses for machine effectiveness. 
• Have altered sandbox options, so now just easy/normal/hard, as i add more options, i will enable a custom option.

Lots of balancing/tweaking needed as have added quite a bit in this update.  Will probably get a little update out in a week or so after playtesting. Also arrived at v0.0.0.100 (that's 100 commits on my game), hopefully getting somewhere!
