Update GIT develop branch

I’ve updated the develop branch of OpenFL to reflect the latest OpenFL 8.9.6 release and have made a new develop-v9 branch to continue v9 development.

Please change to develop-v9 if you are using the OpenFL 9 development version and develop if you are working with OpenFL 8.9.x and would like to contribute changes.

Thank you everyone :slight_smile:
