[v1.1.0] `vobs::trigger_mover` keyframes are not parsed correctly

[lmichaelis]

Keyframes consist of a position and a rotation stored as a quaternion. Currently the rotation is parsed as a glm::mat4 and then converted to a glm::quat which is not correct.

It should be parsed as a quaternion directly. The component order is w, x, y, z.
