Fixed mouse flight

I am posting it at the request of those interested.

This ASI plugin takes the “mouse flight” option from the “useless” category to the “incredibly convenient” category. Now it has become possible and completely playable to control flying vehicles using the mouse. You no longer need 4 hands to operate it.

In order for this to work, you need to enable "mouse flight" in the settings.

Control:

• To lift the plane up, you need to pull the mouse towards you.
• To lower it, pull the mouse away from you.
• To rotate the camera, hold down RMB and rotate the mouse as you please.
