editor and game improvements

- (editor) entities can be rotated
- (editor) asteroids get a random angular velocity
- (editor) level title and author can be specified
- (editor) editor can only be quit when clicking the 'X' button
- (game) smaller asteroids have similar velocities as the previous bigger ones
