Whenever the window is closed, or the close_on_exit system is used, bevy closes all windows then sends the
AppExit
event to shutdown the application. During that time, the systems still run, like our mouse_update system which causes errors on unwrapping of the current window. This just adds a check to see if the window exist.This is my first ever PR to another repo so I don't really know how to structure this or if I even did a decent job (rust noob here) so any feedback is welcome!
