Keyframing: Added ToolSetting for choosing default keyframe type

To make it easier for animators working in a multipass pose-to-pose workflow
when inserting breakdown keyframes and so forth, it is now possible to specify
the "type" of keyframe being created (i.e. the colour of the keyframe, when drawn
in the Dope Sheet).

Usage:
1) Choose the type of keyframe ("Keyframe", "Breakdown", "Extreme", etc.) from
   the new dropdown located between the AutoKeying and KeyingSet widgets on the
   timeline header.
2) Insert keyframes
3) Rejoyce that your newly created keyframes have now been coloured for you already
   in the DopeSheet.

Todo:
* Look into a way of using the actual keyframe colours (from the theme) for the icons
  of these types.
