Improved breakdowns: Various changes and fixes.

Browse Source 
* Revert breakdown_chance to (mostly) its original behaviour.
* Create a new breakdown_chance_factor to hold breakdown_chance
  from improved breakdowns logic.
* Revert airport crash probabilities back to original behaviour, with
  modified behaviour only during emergency landings.
* Low power breakdowns now only reduce the power of the engine which
  has broken down.
* Low power breakdowns no longer reduce speed directly.
* Add callback function to run whenever improved breakdowns setting
  is changed. Reset breakdown_chance_factor where required.
* More whitespace/formatting...
