improve asw_fix_cam

this command makes it possible to fly with a freecam in a demo. Current problem is you have to hold shift and mouse1 to fly, you fly extremely slow and the camera rotates with extremely high sensitivity. WIth this change you dont have to hold shift and mouse1 to fly. Holding shift makes you fly at speed of asw_fix_cam_speed_slow rather than asw_fix_cam_speed_fast. Camera rotation is more bearable and depends on sensitivity. Pressing mouse1 fixes the camera in place. Ive tried making the "Drive..." button in demoui toggle the asw_fix_cam command but not sure how to do it without an engine hack
