Subject: [PATCH] wayvr: Space gravity (#520)

* wayvr: Space gravity (wip)

* dash-frontend: dedicated "Space drag" settings tab, deduplicate overlay shift code in xr&vr, account for gravity shift for static overlays

* space reset & gravity conflict bugfix, add ground friction slider

* Space gravity UI improvements

* space gravity: floor level

* wayvr: space gravity: hide in openvr
