Change open shortcut to Crtl + Alt + K

[Ioxcv12]

Parallax [unfortunately for Kittopia] uses Crtl + P, and I don't think Linx is willing to change the shortcut, so I have made this pull request to request to change it.

I'm willing to do this but am strapped for time this week, so you might not see a build for a few days. But I have no issues with the idea, anyways.

Maybe pressing Ctrl + P should open a popup telling the user that the shortcut has been changed, and then write a file into GameData that prevents the popup from opening again?

(That said, Kittopia has used Ctrl + P for longer than Kopernicus even exists ...)

I've seen your suggestions, so I've readded Crtl + P so that the user doesnt get confused when it doesnt work. Scatterer has the same issue with Alt + F11 and Alt + F10, so Scatterer supports both, and I think that is the best approach.

I've got some time coming up, will look at this and most likely merge it later this week.

Thank you for your patience.

But if you re-add Ctrl + P as is, you still can't open the Parallax GUI without also opening the Kittopia GUI. Hence my suggestion to make it open a one-time notice and then subsequently ignore it.

Oh, I thought that's what he did? Oh well, when I get around to this I can add that if need be. Or you can edit the PR, either way.
