Moving camera is super-ultra-mega fast at high frame rates

[jaydenmilne]

Describe the bug
Camera movement is a fixed amount per frame. This means that when Holodeck is running at a high frame rate (~400fps), movement is almost uncontrollable. The movement should take into account the frame time.

Expected behavior
Pressing w to move forward moves the same amount when running at 30fps as it does at 300 fps.
