Walk Navigation was missing rotation keyframes on confirm (when animation wasnt playing) after rB22bdd08dfd0. Because for walk [in contrast to fly], the cursor is constantly warped (WM_cursor_warp in walkEvent), we cant do something reasonable with comparing mouse positions (to detect rotation) when mouse comes to rest. Now remember if rotation changed at any time. Also tweaked the insertion for location keyframes (which was always happening even if the camera did not move), now checking the real dvec (instead on relying on speed) Reviewed By: dfelinto Maniphest Tasks: T70585 Differential Revision: https://developer.blender.org/D6018
