Fixes stationary walks in SpiralNavigation (#813)

* Fixed sleep to use floats again

* Fixed sleep to use floats again #2

* Refactored jitter to have its own function to be used elsewhere

* Fixes SpiralNavigation skipping waypoints

* Fixing stationary movements

* Improved StepWalker
(distances lower than speed should be walked directly)
