Fixes alien humanoid custom pixel shift being reset by life(). Refactors how pixel reinitialisation (when standing or lying or during animations) is done. Adding get_standard_pixel_y_offset() proc (and same for x), removing lying_pixel_y_offset var from all mobs, adding custom_pixel_x_offset (and y) so Wjohnston can play with his aliens.
