"Auto" option for Keyframe.easing

Browse Source 
This option (alongside the Ease In/Out/InOut options already available) aims to make it
easier to get an initial curve that looks closer to the one you were expecting, by
automatically picking whether Ease In or Ease Out should be used based on the type of
interpolation being used for the curve segment in question.

Notes:
* The types chosen may need some adjustments (e.g. using ease in-out instead of just ease in)
* This does break compatability with files saved in previous dev builds, but only
  if you were using Bounce/Elastic/Back with "Ease In"
