coming out of mouselook mode should retain camera angle

Steps to reproduce the bug: Go into mouselook (1st-person view) mode and look up at the sun (for example), then escape out of mouselook mode back into 3rd-person mode.

Observed results: The camera angle resets to looking down at the avatar instead of looking up at the sun.

Expected results: The camera should not reset to the default 3rd-person camera angle but should, optionally in preferences, keep the same angle as in 1st-person mode.
