PrincesSize maintenance update

Our project was developed 5 years ago, and the plugins needed to run it changed, so we updated the version to run at modern browsers.

Which of course had some errors and outdated plugins, as updates have.

But the game should be playable again!

There are two known bugs, that stayed since 2015, maybe on the next update i'll check them out:

• UI gets crazy on some devices (should be solvable with the Unity UI system that wasn't introduced yet when this game was made)
• If you push a piece into the show, it will not register as inside. Can be super annoying.

Well, I guess we'll see if people still play it 5 years later, and then we'll go into it.
