Changed armature active bone so it is separate from selection this is consistent with active object, mesh editmode, curves & metaballs.

- active is no longer assumed to be selected.
  this fixes a simple bug - eg: Adding a new armature, entering pose mode and toggling selection failed.
- outliner editbone selection now works like object and pose mode.
- mouse selection sets the bone active even when the tip is selected.
- active, unselected bones draw as wire color with a 15% tint of the selected color.
