Control preset possibility and shield powerup implementation

[hooger]

I created the control preset option (possibility to use multiple kay mapping) to make it possibly to have a controller preset as well. That is a bit stalled...

I also created a shield power up, with icon and some animation.

Thank you very much for your huge engagement! Let us split this pull request into topic specific pull requests. For example a3b1bc changes lines, added by 1be91f.

How about you do a clean pull request containing only the control preset and then a pull request containing only the shield powerup?

Hello,

sry for the late reply. I reordered the commits and moved some unnecessarry ones to a different branch. Now how do I make a pull request from earlier commits? If you could help with this I would gladly create the 2 pull requests for the distinct features.

Thanks in advance, hooger
