Look function camera movement improvements

[Richard-L]

The look function in OL has a very machine like camera movement.

Expected behaviour is a smoother motion with ease in/out behaviour, and moving both higher/lower and closer/farther depending on the chosen angle around Lara. Currently it appears to just pivot from one fixed point around her head. In some scenarios (usually tight places like ground holes you stand in), this can make it very difficult or effectively impossible to look on the ground
