Abstracted behavior related to "orientable" entities

A lot of the stuff that ControllingSystem did to control the player character was moved into the new OrientingSystem. This is so that the player, or any player-like entities, can also be controlled by AI, with the underlying behavior being delegated in the same way as if the player were being controlled by the user.

Fixed the issue where, if the player were blocked while moving horizontally, they would remain blocked even if vertical movement were to remove the collision.

Fixed cases of the player animating incorrectly after performing certain movements.
