Free look update and single stick mode (1.3.0)

Free look: - The previous version of free look that was activated with bumpers has been removed. - Shift (keyboard) / d-pad down (controller) now toggles a free look camera that you can fly around with movement/aim. - Due to free look being remapped, the bumpers now also function as rocket and grapple. Single stick mode: - A new experimental feature in gameplay options will make the left stick both aim and move the character (invert rocket aim is flipped in this mode). A and X face buttons will fire rockets and grapples while in this mode. - When switching single stick mode, a level restart is required for changes to take effect. Bug fixes: - Aim assist trying to lock on to air vents wind has been fixed. - Leaderboard search time has been increased to avoid timing out on lower speed connections.
