Fix issues related to curve locking and pinning

- Prevent insertion of keyframes in locked curves.
  (QDS-2172 means locking, not pinning)
- Unselect keyframes when the curve moves into locking state.
- Make sure that locked curves are always at the bottom of the z-stack
  otherwise they might prevent non-locked keyframes from being selected.
- Use the selection color as background for the whole row of a
  treeview-item if it was selected.
- Always paint the locked/pinned/unlocked/unpinned icons in the treeview.
- Fix wrong mouse-hit-test for the locked/pinned icon hover events.
  The delegate was sometimes wrongly assuming that the mouse is hovering
  over a certain icon
