Update the Minecraft Pi module

[ghost]

I have updated the Minecraft Pi module to be more convenient and relevant.
:)

Thanks - please can you be more specific as to improvements with the packaged version?

I would probably avoid the module rename - saves having an extra update hook to run and it will need to clean up the old folder etc. I think it might just be best to leave it called minecraft for now - if we need the namespace in the future that can be changed then.

The packaged version throws Python 2 out the window as it is legacy stuff now, in favor of Python 3.

Also, the accompanying Python module will be installed globally along with the game.

Thanks. The update hook won't be needed now since the install folder will now exist - I will need to perhaps remove the contents of it though if not empty. If you can remove the update, I will merge and do the folder cleanup bit.

Well, thanks! I just learned a little more about the RetroPie module format!

I made a couple of changes - also keeping the addPort name as just "Minecraft" otherwise you get an additional launch script (which means we would need to clean up the old one - but I'm ok with just plain Minecraft.sh)

Ok.
