Improve visual feedback of selections

- The handles can now take 4 kinds of colors:
   1) Unselected.
   2) Handles influenced by a selected keyframe take the selection-color.
   3) Handles that are about to be moved (the mouse hovers over it) take
      the hover color.
   4) Handles that are about to be indirectly moved (Handles that are influenced by the hover handles)
      take the activate color

- Apply some colors of the Theme to the curve-editor.

- Fixed a drag handle bug. (The bounding box for the handle was wrong)
