[Feature]: Add some sort of indicator to tell when you have launched KSP from CKAN

[Clayell]

Problem

When launching KSP from the "Play" button in CKAN, I often get confused if I have already launched KSP if I try to hit the button but misclick, but I don't want to accidentally launch KSP twice if I already have.

Suggestion

Some sort of visual indicator should pop up when you have hit the "Play" button that tells the user that the button press was successful. Perhaps a sort of green flash across the button could pop open.

There could also be some sort of indicator that detects if KSP is already open (which would help with not installing/deleting mods while the game is open), but this is probably much more complicated.
