Gilles Roudiere 8dad41e395 2D editor GUI input rework. Changes are: 
- The input handling is done into several distinct functions, and the
  code is more consistent.
- The actions' history is more precise ("Edited CanvasItem"
  is now "Rotated CanvasItem","Moved CanvasItem",etc...)
- Fixed a little bug about input key events not forwarded correctly to plugins
- IK is followed by default when you move a bone node, the alt-key allow
  you to move it normally
